Budapest (/ˈbuːdəpɛst/, Hungarian pronunciation: [ˈbudɒpɛʃt]) is the capital and the most populous city of Hungary, and the tenth-largest city in the European Union by population within city limits.^[9][10][11] The city has an estimated population of 1,752,286 over a land area of about 525 square kilometres (203 square miles).^[12] Budapest is both a city and county, and forms the centre of the Budapest metropolitan area, which has an area of 7,626 square kilometres (2,944 square miles) and a population of 3,303,786, comprising 33% of the population of Hungary.^[13][14]

The history of Budapest began when an early Celtic settlement transformed into the Roman town of Aquincum,^[15][16] the capital of Lower Pannonia.^[15] The Hungarians arrived in the territory in the late 9th century.^[17] The area was pillaged by the Mongols in 1241.^[18] Buda, the settlements on the west bank of the river, became one of the centres of Renaissance humanist culture by the 15th century.^[19][20][21] The Battle of Mohács, in 1526, was followed by nearly 150 years of Ottoman rule.^[22] After the reconquest of Buda in 1686, the region entered a new age of prosperity. Pest-Buda became a global city with the unification of Buda, Óbuda, and Pest on 17 November 1873, with the name 'Budapest' given to the new capital.^[12][23] Budapest also became the co-capital of the Austro-Hungarian Empire,^[24] a great power that dissolved in 1918, following World War I. The city was the focal point of the Hungarian Revolution of 1848, the Battle of Budapest in 1945, and the Hungarian Revolution of 1956.^[25][26]

Budapest is an Alpha − global city with strengths in commerce, finance, media, art, fashion, research, technology, education, and entertainment.^[27][28] It is Hungary's financial centre^[29] and was ranked as the second fastest-developing urban economy in Europe.^[30] Budapest is the headquarters of the European Institute of Innovation and Technology,^[31] the European Police College^[32] and the first foreign office of the China Investment Promotion Agency.^[33] Over 40 colleges and universities are located in Budapest, including the Eötvös Loránd University, the Semmelweis University and the Budapest University of Technology and Economics.^[34][35] Opened in 1896,^[36] the city's subway system, the Budapest Metro, serves 1.27 million, while the Budapest Tram Network serves 1.08 million passengers daily.^[37]

Among Budapest's important museums and cultural institutions is the Museum of Fine Arts. Further famous cultural institutions are the Hungarian National Museum, House of Terror, Franz Liszt Academy of Music, Hungarian State Opera House and National Széchényi Library. The central area of the city along the Danube River is classified as a UNESCO World Heritage Site and has several notable monuments, including the Hungarian Parliament, Buda Castle, Fisherman's Bastion, Gresham Palace, Széchenyi Chain Bridge, Matthias Church and the Liberty Statue.^[38] Other famous landmarks include Andrássy Avenue, St. Stephen's Basilica, Heroes' Square, the Great Market Hall, the Nyugati Railway Station built by the Eiffel Company of Paris in 1877 and the second-oldest metro line in the world, the Millennium Underground Railway.^[39] The city also has around 80 geothermal springs,^[40] the largest thermal water cave system,^[41] second largest synagogue, and third largest Parliament building in the world.^[42] Budapest attracts 4.4 million international tourists per year, making it a popular destination in Europe.^[43]

The previously separate towns of Buda, Óbuda, and Pest were in 1873 officially unified^[44] and given the new name Budapest. Before this, the towns together had sometimes been referred to colloquially as "Pest-Buda".^[45][46] Pest has also been sometimes used colloquially as a shortened name for Budapest.^[45]

All varieties of English pronounce the -s- as in the English word pest. The -u in Buda- is pronounced either /u/ like food (as in US: /ˈbuːdəpɛst/^[47]) or /ju/ like cue (as in UK: /ˌb(j)uːdəˈpɛst, ˌbʊd-, ˈb(j)uːdəpɛst, ˈbʊd-/). In Hungarian, the -s- is pronounced /ʃ/ as in wash; in IPA: Hungarian: [ˈbudɒpɛʃt] (listen).

The origin of the names "Buda" and "Pest" is obscure. Buda was

Linguistically, however, a German origin through the Slavic derivative вода (voda, water) is not possible, and there is no certainty that a Turkic word really comes from the word buta ~ buda 'branch, twig'.^[51]

According to a legend recorded in chronicles from the Middle Ages, "Buda" comes from the name of its founder, Bleda, brother of Hunnic ruler Attila.

There are several theories about Pest. One^[52] states that the name derives from Roman times, since there was a local fortress (Contra-Aquincum) called by Ptolemaios "Pession" ("Πέσσιον", iii.7.§ 2).^[53] Another has it that Pest originates in the Slavic word for cave, пещера, or peštera. A third cites пещ, or pešt, referencing a cave where fires burned or a limekiln.^[54]

The first settlement on the territory of Budapest was built by Celts^[15] before 1 AD. It was later occupied by the Romans. The Roman settlement – Aquincum – became the main city of Pannonia Inferior in 106 AD.^[15] At first it was a military settlement, and gradually the city rose around it, making it the focal point of the city's commercial life. Today this area corresponds to the Óbuda district within Budapest.^[55] The Romans constructed roads, amphitheaters, baths and houses with heated floors in this fortified military camp.^[56] The Roman city of Aquincum is the best-conserved of the Roman sites in Hungary. The archaeological site was turned into a museum with inside and open-air sections.^[57]

The Magyar tribes led by Árpád, forced out of their original homeland north of Bulgaria by Tsar Simeon after the Battle of Southern Buh, settled in the territory at the end of the 9th century displacing the founding Bulgarian settlers of the towns of Buda and Pest,^[17][58] and a century later officially founded the Kingdom of Hungary.^[17] Research places the probable residence of the Árpáds as an early place of central power near what became Budapest.^[59] The Tatar invasion in the 13th century quickly proved it is difficult to defend a plain.^[12][17] King Béla IV of Hungary therefore ordered the construction of reinforced stone walls around the towns^[17] and set his own royal palace on the top of the protecting hills of Buda. In 1361 it became the capital of Hungary.^[18][12]

The cultural role of Buda was particularly significant during the reign of King Matthias Corvinus. The Italian Renaissance had a great influence on the city. His library, the Bibliotheca Corviniana, was Europe's greatest collection of historical chronicles and philosophic and scientific works in the 15th century, and second in size only to the Vatican Library.^[12] After the foundation of the first Hungarian university in Pécs in 1367 (University of Pécs), the second one was established in Óbuda in 1395 (University of Óbuda).^[60] The first Hungarian book was printed in Buda in 1473.^[61] Buda had about 5,000 inhabitants around 1500.^[62]

The Ottomans conquered Buda in 1526, as well in 1529, and finally occupied it in 1541.^[63] The Turkish Rule lasted for more than 150 years.^[12] The Ottoman Turks constructed many prominent bathing facilities within the city.^[17] Some of the baths that the Turks erected during their rule are still in use 500 years later (Rudas Baths and Király Baths). By 1547 the number of Christians was down to about a thousand, and by 1647 it had fallen to only about seventy.^[62] The unoccupied western part of the country became part of the Habsburg Monarchy as Royal Hungary.

In 1686, two years after the unsuccessful siege of Buda, a renewed campaign was started to enter the Hungarian capital. This time, the Holy League's army was twice as large, containing over 74,000 men, including German, Croat, Dutch, Hungarian, English, Spanish, Czech, Italian, French, Burgundian, Danish and Swedish soldiers, along with other Europeans as volunteers, artillerymen, and officers. The Christian forces seized Buda, and in the next few years, all of the former Hungarian lands, except areas near Temesvár (Timișoara), were taken from the Turks. In the 1699 Treaty of Karlowitz, these territorial changes were officially recognized to show the end of the rule of the Turks, and in 1718 the entire Kingdom of Hungary was removed from Ottoman rule.

The 19th century was dominated by the Hungarian struggle for independence^[12] and modernisation. The national insurrection against the Habsburgs began in the Hungarian capital in 1848 and was defeated one and a half years later, with the help of the Russian Empire. 1867 was the year of Reconciliation that brought about the birth of Austria-Hungary. This made Budapest the twin capital of a dual monarchy. It was this compromise which opened the second great phase of development in the history of Budapest, lasting until World War I. In 1849 the Chain Bridge linking Buda with Pest was opened as the first permanent bridge across the Danube^[64] and in 1873 Buda and Pest were officially merged with the third part, Óbuda (Old Buda), thus creating the new metropolis of Budapest. The dynamic Pest grew into the country's administrative, political, economic, trade and cultural hub. Ethnic Hungarians overtook Germans in the second half of the 19th century due to mass migration from the overpopulated rural Transdanubia and Great Hungarian Plain. Between 1851 and 1910 the proportion of Hungarians increased from 35.6% to 85.9%, Hungarian became the dominant language, and German was crowded out. The proportion of Jews peaked in 1900 with 23.6%.^[65][66][67] Due to the prosperity and the large Jewish community of the city at the start of the 20th century, Budapest was often called the "Jewish Mecca"^[18] or "Judapest".^[68][69] In 1918, Austria-Hungary lost the war and collapsed; Hungary declared itself an independent republic (Republic of Hungary). In 1920 the Treaty of Trianon partitioned the country, and as a result, Hungary lost over two-thirds of its territory, and about two-thirds of its inhabitants, including 3.3 million out of 15 million ethnic Hungarians.^[70][71]

In 1944, a year before the end of World War II, Budapest was partly destroyed by British and American air raids (first attack 4 April 1944^[72][73][74]). From 24 December 1944 to 13 February 1945, the city was besieged during the Battle of Budapest. Budapest suffered major damage caused by the attacking Soviet and Romanian troops and the defending German and Hungarian troops. More than 38,000 civilians lost their lives during the conflict. All bridges were destroyed by the Germans. The stone lions that have decorated the Chain Bridge since 1852 survived the devastation of the war.^[75]

Between 20% and 40% of Greater Budapest's 250,000 Jewish inhabitants died through Nazi and Arrow Cross Party, during the German occupation of Hungary, from 1944 to early 1945.^[76]

Swiss diplomat Carl Lutz rescued tens of thousands of Jews by issuing Swiss protection papers and designating numerous buildings, including the now famous Glass House (Üvegház) at Vadász Street 29, to be Swiss protected territory. About 3,000 Hungarian Jews found refuge at the Glass House and in a neighboring building. Swedish diplomat Raoul Wallenberg saved the lives of tens of thousands of Jews in Budapest by giving them Swedish protection papers and taking them under his consular protection.^[77] Wallenberg was abducted by the Russians on 17 January 1945 and never regained freedom. Giorgio Perlasca, an Italian citizen, saved thousands of Hungarian Jews posing as a Spanish diplomat.^[78][79] Some other diplomats also abandoned diplomatic protocol and rescued Jews. There are two monuments for Wallenberg, one for Carl Lutz and one for Giorgio Perlasca in Budapest.

Following the liberation of Hungary from Nazi Germany by the Red Army, Soviet military occupation ensued, which ended only in 1991. The Soviets exerted significant influence on Hungarian political affairs. In 1949, Hungary was declared a communist People's Republic (People's Republic of Hungary). The new Communist government considered the buildings like the Buda Castle symbols of the former regime, and during the 1950s the palace was gutted and all the interiors were destroyed (also see Stalin era). On 23 October 1956 citizens held a large peaceful demonstration in Budapest demanding democratic reform. The demonstrators went to the Budapest radio station and demanded to publish their demands. The regime ordered troops to shoot into the crowd. Hungarian soldiers gave rifles to the demonstrators who were now able to capture the building. This initiated the Hungarian Revolution of 1956. The demonstrators demanded to appoint Imre Nagy to be Prime Minister of Hungary. To their surprise, the central committee of the "Hungarian Working People's Party" did so that same evening. This uprising was an anti-Soviet revolt that lasted from 23 October until 11 November. After Nagy had declared that Hungary was to leave the Warsaw Pact and become neutral, Soviet tanks and troops entered the country to crush the revolt. Fighting continued until mid November, leaving more than 3000 dead. A monument was erected at the fiftieth anniversary of the revolt in 2006, at the edge of the City Park. Its shape is a wedge with a 56 angle degree made in rusted iron that gradually becomes shiny, ending in an intersection to symbolize Hungarian forces that temporarily eradicated the Communist leadership.^[80]

From the 1960s to the late 1980s Hungary was often satirically referred to as "the happiest barrack" within the Eastern bloc, and much of the wartime damage to the city was finally repaired. Work on Erzsébet Bridge, the last to be rebuilt, was finished in 1964. In the early 1970s, Budapest Metro's East-West M2 line was first opened, followed by the M3 line in 1976. In 1987, Buda Castle and the banks of the Danube were included in the UNESCO list of World Heritage Sites. Andrássy Avenue (including the Millennium Underground Railway, Hősök tere, and Városliget) was added to the UNESCO list in 2002. In the 1980s, the city's population reached 2.1 million. In recent times a significant decrease in population occurred mainly due to a massive movement to the neighbouring agglomeration in Pest county, i.e., suburbanisation.^[81]

In the last decades of the 20th century the political changes of 1989–90 (Fall of the Iron Curtain) concealed changes in civil society and along the streets of Budapest. The monuments of the dictatorship were removed from public places, into Memento Park. In the first 20 years of the new democracy, the development of the city was managed by its mayor, Gábor Demszky.^[82]

Budapest, strategically placed at the centre of the Carpathian Basin, lies on an ancient route linking the hills of Transdanubia with the Great Plain. By road it is 216 kilometres (134 mi) south-east of Vienna, 545 kilometres (339 mi) south of Warsaw, 1,565 kilometres (972 mi) south-west of Moscow, 1,122 kilometres (697 mi) north of Athens, 788 kilometres (490 mi) north-east of Milan, and 443 kilometres (275 mi) south-east of Prague.^[83]

The 525 square kilometres (203 sq mi) area of Budapest lies in Central Hungary, surrounded by settlements of the agglomeration in Pest county. The capital extends 25 and 29 km (16 and 18 mi) in the north-south, east-west direction respectively. The Danube enters the city from the north; later it encircles two islands, Óbuda Island and Margaret Island.^[12] The third island Csepel Island is the largest of the Budapest Danube islands, however only its northernmost tip is within city limits. The river that separates the two parts of the city is 230 m (755 ft) wide at its narrowest point in Budapest. Pest lies on the flat terrain of the Great Plain while Buda is rather hilly.^[12]

The wide Danube was always fordable at this point because of a small number of islands in the middle of the river. The city has marked topographical contrasts: Buda is built on the higher river terraces and hills of the western side, while the considerably larger Pest spreads out on a flat and featureless sand plain on the river's opposite bank.^[84] Pest's terrain rises with a slight eastward gradient, so the easternmost parts of the city lie at the same altitude as Buda's smallest hills, notably Gellért Hill and Castle Hill.^[85]

The Buda hills consist mainly of limestone and dolomite, the water created speleothems, the most famous ones being the Pálvölgyi cave (total length 7,200 m or 23,600 ft) and the Szemlőhegyi cave (total length 2,200 m or 7,200 ft). The hills were formed in the Triassic Period. The highest point of the hills and of Budapest is János hill, at 527 metres (1,729 feet) above sea level. The lowest point is the line of the Danube which is 96 metres (315 feet) above sea level. Budapest is also rich in green areas. Of the 525 square kilometres (203 square miles) occupied by the city, 83 square kilometres (32 square miles) is green area, park and forest.^[86] The forests of Buda hills are environmentally protected.^[87]

The city's importance in terms of traffic is very central, because many major European roads and European railway lines lead to Budapest.^[85] The Danube was and is still an important water-way and this region in the centre of the Carpathian Basin lies at the cross-roads of trade routes.^[88] Budapest is one of only three capital cities in the world which has thermal springs (the other being Reykjavík in Iceland and Sofia in Bulgaria). Some 125 springs produce 70 million litres (15,000,000 imperial gallons; 18,000,000 US gallons) of thermal water a day, with temperatures ranging up to 58 Celsius. Some of these waters have medicinal effects due to their medically valuable mineral contents.^[85]

Budapest has a humid subtropical climate (Köppen climate classification: Cfa), bordering on a subtropical highland climate (Köppen climate classification: Cfb), and if the 0 degrees Celsius isotherm is used, a both the warm-summer and hot-summer versions of the humid continental climate (Köppen climate classification: Dfa, Dfb), with the city featuring relatively cold winters and warm summers according to the 1971–2000 climatological norm when the 0 °C isotherm is used. The recent shift to humid subtropical climate from a humid continental/oceanic climate, is the result of recent higher temperatures, likely due to global warming. This is a concrete example of climate change where climate classifications are changing all over the world, now and in years to come. Winter (November until early March) can be cold and the city receives little sunshine. Snowfall is fairly frequent in most years, and nighttime temperatures of −10 °C (14 °F) are not uncommon between mid-December and mid-February. The spring months (March and April) see variable conditions, with a rapid increase in the average temperature. The weather in late March and April is often very agreeable during the day and fresh at night. Budapest's long summer – lasting from May until mid-September – is warm or very warm. Sudden heavy showers also occur, particularly in May and June. The autumn in Budapest (mid-September until late October) is characterised by little rain and long sunny days with moderate temperatures. Temperatures often turn abruptly colder in late October. Spring and Autumn are generally mild.

Mean annual precipitation in Budapest is around 23.5 inches (596.9 mm). On average, there are 84 days with precipitation and 1988 hours of sunshine (of a possible 4383) each year.^[3][89][90] From March to October, average sunshine totals are roughly equal to those seen in northern Italy (Venice).

The city lies on the boundary between Zone 6 and Zone 7 in terms of the hardiness zone.^[91][92]

Budapest has architecturally noteworthy buildings in a wide range of styles and from distinct time periods, from the ancient times as Roman City of Aquincum in Óbuda (District III), which dates to around 89 AD, to the most modern Palace of Arts, the contemporary arts museum and concert hall.^[95][96][97]

Most buildings in Budapest are relatively low: in the early 2010s there were around 100 buildings higher than 45 metres (148 ft). The number of high-rise buildings is kept low by building legislation, which is aimed at preserving the historic cityscape and to meet the requirements of the World Heritage Site. Strong rules apply to the planning, authorisation and construction of high-rise buildings and consequently much of the inner city does not have any. Some planners would like see an easing of the rules for the construction of skyscrapers, and the possibility of building skyscrapers outside the city's historic core has been raised.^[98][99]

In the chronological order of architectural styles Budapest represents on the entire timeline. Start with the Roman City of Aquincum represents the ancient architecture.

The next determinative style is the Gothic architecture in Budapest. The few remaining Gothic buildings can be found in the Castle District. Buildings of note are no. 18, 20 and 22 on Országház Street, which date back to the 14th century and No. 31 Úri Street, which has a Gothic façade that dates back to the 15th century. Another buildings with Gothic remains is the Inner City Parish Church, built in the 12th century,^[100] and the Mary Magdalene Church, completed in the 15th century.^[101] The most characteristic Gothic-style buildings are actually Neo-Gothic, like the most well-known Budapest landmarks, the Hungarian Parliament Building^[102] and the Matthias Church, where much of the original material was used (originally built in Romanesque style in 1015).^[103]

The next chapter in the history of human architecture is Renaissance architecture. One of the earliest places to be influenced by the Renaissance style of architecture was Hungary, and Budapest in particular. The style appeared following the marriage of King Matthias Corvinus and Beatrice of Naples in 1476. Many Italian artists, craftsmen and masons came to Buda with the new queen. Today, many of the original renaissance buildings disappeared during the varied history of Buda, but Budapest is still rich in renaissance and neo-renaissance buildings, like the famous Hungarian State Opera House, St. Stephen's Basilica and the Hungarian Academy of Sciences.^[104]

During the Turkish occupation (1541–1686), Islamic culture flourished in Budapest; multiple mosques and baths were built in the city. These were great examples of Ottoman architecture, which was influenced by Muslims from around the world including Turkish, Iranian, Arabian and to a larger extent, Byzantine architecture as well as Islamic traditions. After the Holy League conquered Budapest, they replaced most of the mosques with churches and minarets were turned into bell towers and cathedral spires. At one point the distinct sloping central square in Budapest became a bustling Oriental bazaar, which was filled with "the chatter of camel caravans on their way to Yemen and India".^[105] Budapest is in fact one of the few places in the world with functioning original Turkish bathhouses dating back to the 16th century, like Rudas Baths or Király Baths. Budapest is home to the northernmost place where the tomb of influential Islamic Turkish Sufi Dervish, Gül Baba is found. Various cultures converged in Hungary seemed to coalesce well with each other, as if all these different cultures and architecture styles are digested into Hungary's own way of cultural blend. A precedent to show the city's self-conscious is the top section of the city's main square, currently named as Szechenyi. When Turks came to the city, they built mosques here which was aggressively replaced with Gothic church of St. Bertalan. The rationale of reusing the base of the former Islamic building mosque and reconstruction into Gothic Church but Islamic style architecture over it is typically Islamic are still visible. An official term for the rationale is spolia. The mosque was called the djami of Pasha Gazi Kassim, and djami means mosque in Arabic. After Turks and Muslims were expelled and massacred from Budapest, the site was reoccupied by Christians and reformed into a church, the Inner City Parish Church (Budapest). The minaret and Turkish entranceway were removed. The shape of the architecture is its only hint of exotic past—"two surviving prayer niches facing Mecca and an ecumenical symbol atop its cupola: a cross rising above the Turkish crescent moon".

After 1686, the Baroque architecture designated the dominant style of art in catholic countries from the 17th century to the 18th century.^[106] There are many Baroque-style buildings in Budapest and one of the finest examples of preserved Baroque-style architecture is the Church of St. Anna in Batthyhány square. An interesting part of Budapest is the less touristy Óbuda, the main square of which also has some beautiful preserved historic buildings with Baroque façades. The Castle District is another place to visit where the best-known landmark Buda Royal Palace and many other buildings were built in the Baroque style.^[106]

The Classical architecture and Neoclassical architecture are the next in the timeline. Budapest had not one but two architects that were masters of the Classicist style. Mihály Pollack (1773–1855) and József Hild (1789–1867), built many beautiful Classicist-style buildings in the city. Some of the best examples are the Hungarian National Museum, the Lutheran Church of Budavár (both designed by Pollack) and the seat of the Hungarian president, the Sándor Palace. The most iconic and widely known Classicist-style attraction in Budapest is the Széchenyi Chain Bridge.^[107] Budapest's two most beautiful Romantic architecture buildings are the Great Synagogue in Dohány Street and the Vigadó Concert Hall on the Danube Promenade, both designed by architect Frigyes Feszl (1821–1884). Another noteworthy structure is the Budapest Western Railway Station, which was designed by August de Serres and built by the Eiffel Company of Paris in 1877.^[108]

Art Nouveau came into fashion in Budapest by the exhibitions which were held in and around 1896 and organised in connection with the Hungarian Millennium celebrations.^[109] Art Nouveau in Hungary (Szecesszió in Hungarian) is a blend of several architectural styles, with a focus on Hungary's specialities. One of the leading Art Nouveau architects, Ödön Lechner (1845–1914), was inspired by Indian and Syrian architecture as well as traditional Hungarian decorative designs. One of his most beautiful buildings in Budapest is the Museum of Applied Arts. Another examples for Art Nouveau in Budapest is the Gresham Palace in front of the Chain Bridge, the Hotel Gellért, the Franz Liszt Academy of Music or Budapest Zoo and Botanical Garden.^[95]

The second half of the 20th century also saw, under the communist regime, the construction of blocks of flats (panelház), as in other Eastern European countries. In the 21st century, Budapest faces new challenges in its architecture. The pressure towards the high-rise buildings is unequivocal among today's world cities, but preserving Budapest's unique cityscape and its very diverse architecture, along with green areas, is force Budapest to balance between them. The Contemporary architecture has wide margin in the city. Public spaces attract heavy investment by business and government also, so that the city has gained entirely new (or renovated and redesigned) squares, parks and monuments, for example the city central Kossuth Lajos square, Deák Ferenc square and Liberty Square. Budapest's current urban landscape is one of the modern and contemporary architecture. Numerous landmarks are created in the last decade in Budapest, like the National Theatre, Palace of Arts, Rákóczi Bridge, Megyeri Bridge, Budapest Airport Sky Court among others, and millions of square meters of new office buildings and apartments. But there are still large opportunities in real estate development in the city.^{[110][111][112]}

Most of today's Budapest is the result of a late-nineteenth-century renovation, but the wide boulevards laid out then only bordered and bisected much older quarters of activity created by centuries of Budapest's city evolution. Budapest's vast urban area is often described using a set of district names. These are either informal designations, reflect the names of villages that have been absorbed by sprawl, or are superseded administrative units of former boroughs.^[114] Such names have remained in use through tradition, each referring to a local area with its own distinctive character, but without official boundaries.^[115] Originally Budapest had 10 districts after coming into existence upon the unification of the three cities in 1873. Since 1950, Greater Budapest has been divided into 22 boroughs (and 23 since 1994). At that time there were changes both in the order of districts and in their sizes. The city now consists of 23 districts, 6 in Buda, 16 in Pest and 1 on Csepel Island between them. The city centre itself in a broader sense comprises the District V, VI, VII, VIII, IX^[116] and XIII on the Pest side, and the I, II, XI and XII on the Buda side of the city.^[117]

District I is a small area in central Buda, including the historic Buda Castle. District II is in Buda again, in the northwest, and District III stretches along in the northernmost part of Buda. To reach District IV, one must cross the Danube to find it in Pest (the eastern side), also at north. With District V, another circle begins, it is located in the absolute centre of Pest. Districts VI, VII, VIII and IX are the neighbouring areas to the east, going southwards, one after the other. District X is another, more external circle also in Pest, while one must jump to the Buda side again to find Districts XI and XII, going northwards. No more districts remaining in Buda in this circle, we must turn our steps to Pest again to find Districts XIII, XIV, XV, XVI, XVII, XVIII, XIX and XX (mostly external city parts), almost regularly in a semicircle, going southwards again. District XXI is the extension of the above route over a branch of the Danube, the northern tip of a long island south from Budapest. District XXII is still on the same route in southwest Buda, and finally District XXIII is again in southernmost Pest, irregular only because it was part of District XX until 1994.^[118]

Budapest is the most populous city in Hungary and one of the largest cities in the European Union, with a growing number of inhabitants, estimated at 1,763,913 in 2019,^[131] whereby inward migration exceeds outward migration.^[9] These trends are also seen throughout the Budapest metropolitan area, which is home to 3.3 million people.^[132][133] This amounts to about 34% of Hungary's population. In 2014, the city had a population density of 3,314 people per square kilometre (8,580/sq mi), rendering it the most densely populated of all municipalities in Hungary. The population density of Elisabethtown-District VII is 30,989/km² (80,260/sq mi), which is the highest population density figure in Hungary and one of the highest in the world, for comparison the density in Manhattan is 25,846/km².^[134]

Budapest is the fourth most "dynamically growing city" by population in Europe,^[135] and the Euromonitor predicts a population increase of almost 10% between 2005 and 2030.^[136] The European Observation Network for Territorial Development and Cohesion says Budapest's population will increase by 10% to 30% only due to migration by 2050.^[137] A constant inflow of migrants in recent years has fuelled population growth in Budapest. Productivity gains and the relatively large economically active share of the population explain why household incomes have increased in Budapest to a greater extent than in other parts of Hungary. Higher incomes in Budapest are reflected in the lower share of expenditure the city's inhabitants allocate to necessity spending such as food and non-alcoholic drinks.^[132]

Budapest has many municipal parks and most have playgrounds for children and seasonal activities like skating in the winter and boating in the summer. Access from the city center is quick and easy with the Millennium Underground. Budapest has a complex park system, with various lands operated by the Budapest City Gardening Ltd.^[181] The wealth of greenspace afforded by Budapest's parks is further augmented by a network of open spaces containing forest, streams, and lakes that are set aside as natural areas which lie not far from the inner city, including the Budapest Zoo and Botanical Garden (established in 1866) in the City Park.^[182] The most notable and popular parks in Budapest are the City Park which was established in 1751 (302 acres) along with Andrássy Avenue,^[183] the Margaret Island in the Danube (238 acres or 96 hectares),^[184] the People's Park, the Római Part, and the Kopaszi Dam.^[185]

The Buda Hills also offer a variety of outdoor activities and views. A place frequented by locals is Normafa, offering activities for all seasons. With a modest ski run, it is also used by skiers and snow boarders – if there is enough snowfall in winter.

A number of islands can be found on the Danube in Budapest:

The islands of Palotai Island, Nép Island, and Háros Island also formerly existed within the city, but have been joined to the mainland.

The Ínség Rock (Hungarian: Ínség-szikla) is a reef in the Danube close to the shore under the Gellért Hill. It is only exposed during drought periods when the river level is very low.

Just outside the city boundary to the north lies the large Szentendre Island (Hungarian: Szentendrei-sziget) and the much smaller Lupa Island (Hungarian: Lupa-sziget).

One of the reasons the Romans first colonised the area immediately to the west of the River Danube and established their regional capital at Aquincum (now part of Óbuda, in northern Budapest) is so that they could utilise and enjoy the thermal springs. There are still ruins visible today of the enormous baths that were built during that period. The new baths that were constructed during the Turkish period (1541–1686) served both bathing and medicinal purposes, and some of these are still in use to this day.^[186][187]

Budapest gained its reputation as a city of spas in the 1920s, following the first realisation of the economic potential of the thermal waters in drawing in visitors. Indeed, in 1934 Budapest was officially ranked as a "City of Spas". Today, the baths are mostly frequented by the older generation, as, with the exception of the "Magic Bath" and "Cinetrip" water discos, young people tend to prefer the lidos which are open in the summer.

Construction of the Király Baths started in 1565, and most of the present-day building dates from the Turkish period, including most notably the fine cupola-topped pool.

The Rudas Baths are centrally placed – in the narrow strip of land between Gellért Hill and the River Danube – and also an outstanding example of architecture dating from the Turkish period. The central feature is an octagonal pool over which light shines from a 10 metres (33 ft) diameter cupola, supported by eight pillars.

The Gellért Baths and Hotel were built in 1918, although there had once been Turkish baths on the site, and in the Middle Ages a hospital. In 1927, the Baths were extended to include the wave pool, and the effervescent bath was added in 1934. The well-preserved Art Nouveau interior includes colourful mosaics, marble columns, stained glass windows and statues.

The Lukács Baths are also in Buda and are also Turkish in origin, although they were only revived at the end of the 19th century. This was also when the spa and treatment centre were founded. There is still something of an atmosphere of fin-de-siècle about the place, and all around the inner courtyard there are marble tablets recalling the thanks of patrons who were cured there. Since the 1950s it has been regarded as a centre for intellectuals and artists.

The Széchenyi Baths are one of the largest bathing complexes in all Europe, and the only "old" medicinal baths to be found in the Pest side of the city. The indoor medicinal baths date from 1913 and the outdoor pools from 1927. There is an atmosphere of grandeur about the whole place with the bright, largest pools resembling aspects associated with Roman baths, the smaller bath tubs reminding one of the bathing culture of the Greeks, and the saunas and diving pools borrowed from traditions emanating in northern Europe. The three outdoor pools (one of which is a fun pool) are open all year, including winter. Indoors there are over ten separate pools, and a whole host of medical treatments is also available. The Szécheny Baths are built in modern Renaissance style.

Budapest is served by Budapest Ferenc Liszt International Airport (BUD) (named after Franz Liszt, the notable Hungarian composer), one of the busiest airports in Central and Eastern Europe, located 16 kilometres (9.9 mi) east-southeast of the centre of Budapest, in the District XVIII. The airport offers international connections among all major European cities, and also to North America, Africa, Asia and the Middle East. As Hungary's busiest airport, it handles nearly all of the country's air passenger traffic. Budapest Liszt Ferenc handled around 250 scheduled flights daily in 2013, and an ever-rising number of charters. London, Brussels, Frankfurt, Munich, Paris, and Amsterdam are the busiest international connections respectively, while Toronto, Montreal, Dubai, Doha and Alicante are the most unusual in the region.^[188] Today the airport serves as a base for Ryanair, Wizz Air, Budapest Aircraft Service, CityLine Hungary, Farnair Hungary and Travel Service Hungary among others. The airport is accessible via public transportation from the city centre by the Metro line 3 and then the airport bus No. 200E.^[189]

As part of a strategic development plan, €561 million have been spent on expanding and modernising the airport infrastructure until December 2012. Most of these improvements are already completed,^[190] the postponed ones are the new cargo area and new piers for terminal 2A and 2B, but these development are on standby also, and will start immediately, when the airport traffic will reach the appropriate level. SkyCourt, the newest, state-of-the-art building between the 2A and 2B terminals with 5 levels. Passenger safety checks were moved here along with new baggage classifiers and the new Malév and SkyTeam business lounges, as well as the first MasterCard lounge in Europe.^[191]

Public transit in Budapest is provided by the Centre for Budapest Transport (BKK, Budapesti Közlekedési Központ), one of the largest transportation authorities in Europe.^[192] BKK operates 4 metro lines (including the historic Line 1, the oldest underground railway in continental Europe), 5 suburban railway lines, 33 tram lines, 15 trolleybus lines, 264 bus lines (including 40 night routes), 4 boat services, and BuBi, a smart bicycle sharing network.

The aim is 80%–20% by 2030 in accordance with the strategy of BKK.^[194]

The development of complex intelligent transportation system in the city is advancing; the application of smart traffic lights is widespread, they are GPS and computer controlled and give priority to the GPS connected public transport vehicles automatically, as well as the traffic is measured and analyzed on the roads and car drivers informed about the expected travel time and traffic by intelligent displays (EasyWay project).^[195] Public transport users are immediately notified of any changes in public transport online, on smartphones and on PIDS displays, as well car drivers can keep track of changes in traffic and road management in real-time online and on smartphones through the BKK Info.^[196][197] As well all vehicles can be followed online and on smartphones in real-time throughout the city with the Futár PIDS system,^[198] while the continuous introducing of integrated e-ticket system will help the measurement of passenger numbers on each line and the intelligent control of service frequency.

The development of Futár, the citywide real-time passenger information system and real-time route planner is finished already and now all of the public transport vehicle is connected via satellite system. The real-time information of trams, buses and trolleybuses are available for both the operators in the control room and for all the passengers in all stops on smartphone and on city street displays.^[199] The implementation of latest generation automated fare collection and e-ticket system with NFC compatibility and reusable contactless smart cards for making electronic payments in online and offline systems in Budapest is started in 2014, the project is implemented and operated by the operator of Hong Kong Octopus card jointly with one of the leading European companies of e-ticket and automated fare collection, Scheidt & Bachmann.^[200] The deployment of 300 new digital contactless ticket vending machine will be finished by the end of 2014 in harmonization with the e-ticket system.^[201]

The tram lines no. 4 and 6 are the busiest city tram lines in the world,^[202] with one of the world's longest trams (54-metre long Siemens Combino) running at 2–3 minute intervals at peak time and 4–5 minutes off-peak. Day services are usually from 4 am until between 11 pm and 0:30 am.^[166] Hungarian State Railways operates an extensive network of commuter rail services, their importance in the suburban commuter passenger traffic is significant, but in travel within the city is limited. The organiser of public transport in Budapest is the municipal corporation Centre for Budapest Transport (Budapesti Közlekedési Központ – BKK), that is responsible for planning and organising network and services, planning and developing tariff concepts, attending to public service procurer duties, managing public service contracts, operating controlling and monitoring systems, setting and monitoring service level agreements related to public transport, attending to customer service duties, selling and monitoring tickets and passes, attending to integrated passenger information duties, unified Budapest-centric traffic control within public transport, attending to duties related to river navigation, plus the management of Budapest roads, operating taxi stations, unified control of bicycle traffic development in the capital, preparing parking strategy and developing an operational concept, preparation of road traffic management, developing an optimal traffic management system, organising and co-ordinating road reconstruction and more, in short, everything which is related to transport in the city.^[203]

Budapest is the most important Hungarian road terminus, all of the major highways and railways end within the city limits. The road system in the city is designed in a similar manner to that of Paris, with several ring roads, and avenues radiating out from the center. Ring road M0 around Budapest is nearly completed, with only one section missing on the west side due to local disputes. Currently the ring road is 80 kilometres (50 miles) in length, and once finished it will be 107 kilometres (66 mi) of highway in length.

The city is a vital traffic hub because all major European roads and European railway lines lead to Budapest.^[85] The Danube was and is still today an important water-way and this region in the centre of the Carpathian Basin lies at the cross-roads of trade routes.^[88] Hungarian main line railways are operated by Hungarian State Railways. There are three main railway station in Budapest, Keleti (Eastern), Nyugati (Western) and Déli (Southern), operating both domestic and international rail services. Budapest is one of the main stops of the on its Central and Eastern European route.^[204] There is also a suburban rail service in and around Budapest, three lines of which are operated under the name HÉV.

The river Danube flows through Budapest on its way from Germany to the Black Sea. The river is easily navigable and so Budapest historically has a major commercial port at Csepel District and at New Pest District also.
