Basel (/ˈbɑːzəl/ BAH-zəl, German: [ˈbaːzl̩] (listen)) or Basle (/bɑːl/ BAHL; French: Bâle [bɑl]; Italian: Basilea [baziˈlɛːa]; Romansh: Basilea [baziˈleːa] (listen)) is a city in northwestern Switzerland on the river Rhine. Basel is Switzerland's third-most-populous city (after Zürich and Geneva) with about 180,000 inhabitants.^[5]

Located where the Swiss, French and German borders meet, Basel also has suburbs in France and Germany. As of 2016, the Swiss Basel agglomeration was the third-largest in Switzerland, with a population of 541,000^[6] in 74 municipalities in Switzerland (municipal count as of 2018).^[7] The initiative Trinational Eurodistrict Basel (TEB) of 62 suburban communes including municipalities in neighboring countries, counted 829,000 inhabitants in 2007.^[8]

The official language of Basel is (the Swiss variety of Standard) German, but the main spoken language is the local Basel German dialect.

The city is known for its many internationally renowned museums, ranging from the Kunstmuseum, the first collection of art accessible to the public in Europe (1661) and the largest museum of art in the whole of Switzerland, to the Fondation Beyeler (located in Riehen). The University of Basel, Switzerland's oldest university (founded in 1460), and the city's centuries-long commitment to humanism, have made Basel a safe haven at times of political unrest in other parts of Europe for such notable people as Erasmus of Rotterdam, the Holbein family, Friedrich Nietzsche and in the 20th century also Hermann Hesse and Karl Jaspers.

The city of Basel is Switzerland's second-largest economic centre after the city of Zürich and has the highest GDP per capita in the country, ahead of the cantons of Zug and Geneva.^[9] In terms of value, over 94% of Basel City's goods exports are in the chemical and pharmaceutical sectors. With production facilities located in the neighboring Schweizerhalle, Basel accounts for 20% of Swiss exports and generates one third of the national product.^[10]

Basel has been the seat of a Prince-Bishopric since the 11th century, and joined the Swiss Confederacy in 1501. The city has been a commercial hub and an important cultural centre since the Renaissance, and has emerged as a centre for the chemical and pharmaceutical industries in the 20th century. In 1897, Basel was chosen by Theodor Herzl as the location for the first World Zionist Congress, and altogether the congress has been held there ten times over a time span of 50 years, more than in any other location. The city is also home to the world headquarters of the Bank for International Settlements.

In 2019 Basel, was ranked among the ten most liveable cities in the world by Mercer together with Zürich and Geneva.^[11]

There are traces of a settlement at the Rhine knee from the early La Tène period (5th century BC). In the 2nd century BC, there was a village of the Raurici at the site of Basel-Gasfabrik, to the northwest of the Old City, likely identical with the town of Arialbinnum mentioned on the Tabula Peutingeriana.^[12] The unfortified settlement was abandoned in the 1st century BC in favour of an oppidum on the site of Basel Minster, probably in reaction to the Roman invasion of Gaul.

In Roman Gaul, Augusta Raurica was established some 20 km (12 mi) from Basel as the regional administrative centre, while a castra (fortified camp) was built on the site of the Celtic oppidum. The city of Basel eventually grew around the castra. In AD 83, Basel was incorporated into the Roman province of Germania Superior. Roman control over the area deteriorated in the 3rd century, and Basel became an outpost of the Provincia Maxima Sequanorum formed by Diocletian.

The Germanic confederation of the Alemanni attempted to cross the Rhine several times in the 4th century, but were repelled; one such event was the Battle of Solicinium (368). However, in the great invasion of AD 406, the Alemanni appear to have crossed the Rhine river a final time, conquering and then settling what is today Alsace and a large part of the Swiss Plateau. From that time, Basel has been an Alemannic settlement.

The Duchy of Alemannia fell under Frankish rule in the 6th century, and by the 7th century, the former bishopric of Augusta Raurica was re-established as the Bishopric of Basel. Based on the evidence of a third solidus with the inscription Basilia fit, Basel seems to have minted its own coins in the 7th century.^[13] Under bishop Haito, the first cathedral was built on the site of the Roman castle, later replaced by a Romanesque structure consecrated in 1019. At the partition of the Carolingian Empire, Basel was first given to West Francia, but it passed to East Francia with the treaty of Meerssen of 870.

The city was plundered and destroyed by a Magyar invasion in 917. The rebuilt city became part of Upper Burgundy, and as such was incorporated into the Holy Roman Empire in 1032.

From the donation by Rudolph III of Burgundy^[14] of the Moutier-Grandval Abbey and all its possessions to Bishop Adalbero II of Metz in 999 until the Reformation, Basel was ruled by prince-bishops (see Bishop of Basel,^[15] whose memory is preserved in the crosier shown on the Basel coat of arms – see above).

In 1019, the construction of the cathedral of Basel (known locally as the Münster) began under Henry II, Holy Roman Emperor.^[16] In 1225–1226, a bridge, now known as the Middle Bridge, was constructed by Bishop Heinrich von Thun and Lesser Basel (Kleinbasel) founded as a bridgehead to protect the bridge. The bridge was largely funded by Basel's Jewish community who had settled there a century earlier.^[17] For many centuries to come Basel possessed the only permanent bridge over the river "between Lake Constance and the sea".

The Bishop also allowed the furriers to establish a guild in 1226. Eventually about 15 guilds were established in the 13th century. They increased the town's, and hence the bishop's, reputation, influence, and income from the taxes and duties on goods in Basel's expanding market.^[17]

The plague came to Europe in 1347, but did not reach Basel until June 1349. The guilds, asserting that the Jews were responsible—several had been tortured and confessed—demanded they be executed, which the Council did in January 1349, except for a few who escaped to Alsace.^[17] During the Basel massacre, 600 Jews were murdered. They were shackled inside a wooden barn on an island in the Rhine, which was set afire. The few survivors - young orphans - were forcibly converted to Christianity. The council then forbade Jews in Basel for 200 years, except that their money was helpful in rebuilding after the Basel earthquake of 1356 which destroyed much of the city along with a number of castles in the vicinity. The city offered courts to nobles as an alternative to rebuilding their castles, in exchange for the nobles' military protection of the city.

In 1412 (or earlier), the well-known Gasthof zum Goldenen Sternen was established. Basel became the focal point of western Christendom during the 15th century Council of Basel (1431–1449), including the 1439 election of antipope Felix V. In 1459, Pope Pius II endowed the University of Basel, where such notables as Erasmus of Rotterdam and Paracelsus later taught. At the same time the new craft of printing was introduced to Basel by apprentices of Johann Gutenberg.

The Schwabe publishing house was founded in 1488 by Johannes Petri and is the oldest publishing house still in business. Johann Froben also operated his printing house in Basel and was notable for publishing works by Erasmus.^[18] In 1495, Basel was incorporated into the Upper Rhenish Imperial Circle; the Bishop of Basel was added to the Bench of the Ecclesiastical Princes. In 1500 the construction of the Basel Münster was finished. In 1521 so was the bishop. The Council, under the supremacy of the guilds, explained that henceforth they would only give allegiance to the Swiss Confederation, to whom the bishop appealed but in vain.^[17]

The city had remained neutral through the Swabian War of 1499 despite being plundered by soldiers on both sides. The Treaty of Basel ended the war and granted the Swiss confederates exemptions from the emperor Maximillian's taxes and jurisdictions, separating Switzerland de facto from the Holy Roman Empire.^[19]

On 9 June 1501, Basel joined the Swiss Confederation as its eleventh canton.^[20] It was the only canton that was asked to join, not the other way round. Basel had a strategic location, good relations with Strasbourg and Mulhouse, and control of the corn imports from Alsace, whereas the Swiss lands were becoming overpopulated and had few resources. A provision of the Charter accepting Basel required that in conflicts among the other cantons it was to stay neutral and offer its services for mediation.^[21][22]

In 1503, the new bishop Christoph von Utenheim refused to give Basel a new constitution; whereupon, to show its power, the city began to build a new city hall.^[17]

In 1529, the city became Protestant under Oecolampadius and the bishop's seat was moved to Porrentruy. The bishop's crook was however retained as the city's coat of arms. For centuries to come, a handful of wealthy families collectively referred to as the "Daig" played a pivotal role in city affairs as they gradually established themselves as a de facto city aristocracy.

The first edition of Christianae religionis institutio (Institutes of the Christian Religion – John Calvin's great exposition of Calvinist doctrine) was published at Basel in March 1536.^[23]

In 1544, Johann von Brugge, a rich Dutch Protestant refugee, was given citizenship and lived respectably until his death in 1556, then buried with honors. His body was exhumed and burnt at the stake in 1559 after it was discovered that he was the Anabaptist David Joris.^[17]

In 1543, De humani corporis fabrica, the first book on human anatomy, was published and printed in Basel by Andreas Vesalius (1514–1564).^[24]

There are indications Joachim Meyer, author of the influential 16th-century martial arts text Kunst des Fechten ("The Art of Fencing"), came from Basel. In 1662 the Amerbaschsches Kabinett was established in Basel as the first public museum of art. Its collection became the core of the later Basel Museum of Art.

The Bernoulli family, which included important 17th- and 18th-century mathematicians such as Jakob Bernoulli, Johann Bernoulli and Daniel Bernoulli, were from Basel. The 18th-century mathematician Leonhard Euler was born in Basel and studied under Johann Bernoulli.

In 1792, the Republic of Rauracia, a revolutionary French client republic, was created. It lasted until 1793.^[25] After three years of political agitation and a short civil war in 1833 the disadvantaged countryside seceded from the Canton of Basel, forming the half canton of Basel-Landschaft.^[26]

On 3 July 1874, Switzerland's first zoo, the Zoo Basel, opened its doors in the south of the city towards Binningen.

In 1897 the first World Zionist Congress was held in Basel. Altogether the World Zionist Congress was held in Basel ten times, more than in any other city in the world.^[27]

On 16 November 1938, the psychedelic drug LSD was first synthesized by Swiss chemist Albert Hofmann at Sandoz Laboratories in Basel.

Basel has often been the site of peace negotiations and other international meetings. The Treaty of Basel (1499) ended the Swabian War. Two years later Basel joined the Swiss Confederation. The Peace of Basel in 1795 between the French Republic and Prussia and Spain ended the First Coalition against France during the French Revolutionary Wars. In more recent times, the World Zionist Organization held its first congress in Basel from August 29 through August 31, 1897. Because of the Balkan Wars, the (Socialist) Second International held an extraordinary congress at Basel in 1912. In 1989, the Basel Convention was opened for signature with the aim of preventing the export of hazardous waste from wealthy to developing nations for disposal.

The name of Basel is derived from the Roman-era toponym Basilia, first recorded in the 3rd century. It is presumably derived from the personal Greek name Basilius.^[28] The Old French form Basle was adopted into English, and developed into the modern French Bâle. The Icelandic name Buslaraborg goes back to the 12th century Leiðarvísir og borgarskipan chronicle.

Basel has an area, as of 2009, of 23.91 square kilometers (9.23 sq mi). Of this area, 0.95 km2 (0.37 sq mi) or 4.0% is used for agricultural purposes, while 0.88 km2 (0.34 sq mi) or 3.7% is forested. Of the rest of the land, 20.67 km2 (7.98 sq mi) or 86.4% is settled (buildings or roads), 1.45 km2 (0.56 sq mi) or 6.1% is either rivers or lakes.^[29]

Of the built up area, industrial buildings made up 10.2% of the total area while housing and buildings made up 40.7% and transportation infrastructure made up 24.0%. Power and water infrastructure as well as other special developed areas made up 2.7% of the area while parks, green belts and sports fields made up 8.9%. Out of the forested land, all of the forested land area is covered with heavy forests. Of the agricultural land, 2.5% is used for growing crops and 1.3% is pastures. All the water in the municipality is flowing water.^[29]

Under the Köppen climate classification, Basel features a temperate oceanic (Köppen: Cfb) climate.^[30] The city averages 120.4 days of rain or snow annually and on average receives 842 mm (33.1 in) of precipitation. The wettest month is May during which time Basel receives an average of 99 mm (3.9 in) of rain. The month with the most days of precipitation is also May, with an average of 12.4 days. The driest month of the year is February with an average of 45 mm (1.8 in) of precipitation over 8.4 days.^[31]

The city of Basel functions as the capital of the Swiss half-canton of Basel-Stadt, though several of its suburbs are located in the half-canton of Basel-Landschaft or the canton of Aargau. Others are even located in France and Germany.

The canton Basel-Stadt consists of three municipalities: Riehen, Bettingen, and the city Basel itself. The political structure and agencies of the city and the canton are identical.

The city itself has 19 quarters:

The blazon of the municipal coat of arms is In Silber ein schwarzer Baselstab.^[34] (Argent, a staff of Basel sable)

(For "staff", see Heraldsnet website ^[133] .)

The canton's executive, the Executive Council (Regierungsrat), consists of seven members for a mandate period of 4 years. They are elected by any inhabitant valid to vote on the same day as the parliament, but by means of a system of Majorz, and operates as a collegiate authority. The president (German: Regierungspräsident(in)) is elected as such by a public election, while the heads of the other departments are appointed by the collegiate. The current president is Dr Guy Morin. The executive body holds its meetings in the red Town Hall (German: Rathaus) on the central Marktplatz. The building was built in 1504–1514.

As of 2016, Basel's Executive Council is made up of three representatives of the SP (Social Democratic Party), and one member each of Green Alliance of Basel (GB) (who is the president), FDP (Free Democratic Party), LDP (Liberal-Demokratische Partei of Basel), and CVP (Christian Democratic Party), giving the left parties a combined four out of seven seats.^[35] The last election was held on 23 October and 27 November 2016.^[36]

Barbara Schüpbach-Guggenbühlis is State Chronicler (Staatsschreiberin) since 2009, and Marco Greiner is Head of Communication (Regierungssprecher) and Vice State Chronicler (Vizestaatsschreiber) since 2007 for the Executive Council.

The parliament, the Grand Council of Basel-Stadt (Grosser Rat), consists of 100 seats, with members (called in German: Grossrat/Grossrätin) elected every 4 years. The sessions of the Grand Council are public. Unlike the members of the Executive Council, the members of the Grand Council are not politicians by profession, but they are paid a fee based on their attendance. Any resident of Basel allowed to vote can be elected as a member of the parliament. The delegates are elected by means of a system of Proporz, and political parties must have surpassed an election quorum of 4% per election district in order to enter the council, but this will end with the next election in 2020.^[37] The legislative body holds its meetings in the red Town Hall (Rathaus).

The last election was held on 23 October 2016 for the mandate period (Legislatur) of 2017–2021.^[36] As of 1 February 2017, the Grand Council consist of 35 members of the Social Democratic Party (SP), 15 members of the Swiss People's Party (SVP), 13 Grünes Bündnis (GB) (a collaboration of the Green Party (GPS), its junior party, and Basels starke Alternative (BastA!)), 15 Liberal-Demokratische Partei (LDP) and its junior party, 10 The Liberals (FDP) and its junior party, the representative of the Aktive Bettingen (AB) is associated to the parliamentary group (Fraktion) of the FDP, 8 (7/1) Christian Democratic People's Party (CVP)/Evangelical People's Party (EVP), and 3 Green Liberal Party (GLP).^[38]

The left parties missed an absolute majority by two seats.

On 18 October 2015, in the federal election the most popular party was the Social Democratic Party (SP) which received two seats with 33.5% of the votes. The next three most popular parties were the FDP (21.4%), the SVP (17.6%), and the Green Party (GPS) (11.2%), each with one seat. In the federal election, a total of 57,304 votes were cast, and the voter turnout was 50.4%.^[39]

On 18 October 2015, in the federal election State Councilor (German: Ständerätin) Anita Fetz, member of the Social Democratic Party      (SP), was re-elected in the first round as single representative of the canton of Basel-Stadt in the national Council of States (German: Ständerat) with an absolute majority of 35'842 votes. She has been a member of it since 2003.^[41]

Basel has two sister cities and a twinning among two states:^[42]

Basel has a population (as of August 2019) of 177,654.^[43] As of 2015, 35.5% of the population are resident foreign nationals.^[44] Over the last 10 years (1999–2009 ) the population has changed at a rate of -0.3%. It has changed at a rate of 3.2% due to migration and at a rate of -3% due to births and deaths.^[45]

Of the population in the municipality 58,560 or about 35.2% were born in Basel and lived there in 2000. There were 1,396 or 0.8% who were born in the same canton, while 44,874 or 26.9% were born somewhere else in Switzerland, and 53,774 or 32.3% were born outside of Switzerland.^[46]

In 2008 there were 898 live births to Swiss citizens and 621 births to non-Swiss citizens, and in same time span there were 1,732 deaths of Swiss citizens and 175 non-Swiss citizen deaths. Ignoring immigration and emigration, the population of Swiss citizens decreased by 834 while the foreign population increased by 446. There were 207 Swiss men and 271 Swiss women who emigrated from Switzerland. At the same time, there were 1756 non-Swiss men and 1655 non-Swiss women who immigrated from another country to Switzerland. The total Swiss population change in 2008 (from all sources, including moves across municipal borders) was an increase of 278 and the non-Swiss population increased by 1138 people. This represents a population growth rate of 0.9%.^[47]

As of 2000, there were 70,502 people who were single and never married in the municipality. There were 70,517 married individuals, 12,435 widows or widowers and 13,104 individuals who are divorced.^[46]

As of 2000 the average number of residents per living room was 0.59 which is about equal to the cantonal average of 0.58 per room.^[45] In this case, a room is defined as space of a housing unit of at least 4 m2 (43 sq ft) as normal bedrooms, dining rooms, living rooms, kitchens and habitable cellars and attics.^{[48] []} About 10.5% of the total households were owner occupied, or in other words did not pay rent (though they may have a mortgage or a rent-to-own agreement).^{[48] []} As of 2000, there were 86,371 private households in the municipality, and an average of 1.8 persons per household.^[45] There were 44,469 households that consist of only one person and 2,842 households with five or more people. Out of a total of 88,646 households that answered this question, 50.2% were households made up of just one person and there were 451 adults who lived with their parents. Of the rest of the households, there are 20,472 married couples without children, 14,554 married couples with children There were 4,318 single parents with a child or children. There were 2,107 households that were made up of unrelated people and 2,275 households that were made up of some sort of institution or another collective housing.^[46]

In 2000 there were 5,747 single family homes (or 30.8% of the total) out of a total of 18,631 inhabited buildings. There were 7,642 multi-family buildings (41.0%), along with 4,093 multi-purpose buildings that were mostly used for housing (22.0%) and 1,149 other use buildings (commercial or industrial) that also had some housing (6.2%). Of the single family homes 1090 were built before 1919, while 65 were built between 1990 and 2000. The greatest number of single family homes (3,474) were built between 1919 and 1945.^[49]

In 2000 there were 96,640 apartments in the municipality. The most common apartment size was 3 rooms of which there were 35,958. There were 11,957 single room apartments and 9,702 apartments with five or more rooms. Of these apartments, a total of 84,675 apartments (87.6% of the total) were permanently occupied, while 7,916 apartments (8.2%) were seasonally occupied and 4,049 apartments (4.2%) were empty.^[49] As of 2009, the construction rate of new housing units was 2.6 new units per 1000 residents.^[45]

As of 2003 the average price to rent an average apartment in Basel was 1118.60 Swiss francs (CHF) per month (US$890, £500, €720 approx. exchange rate from 2003). The average rate for a one-room apartment was 602.27 CHF (US$480, £270, €390), a two-room apartment was about 846.52 CHF (US$680, £380, €540), a three-room apartment was about 1054.14 CHF (US$840, £470, €670) and a six or more room apartment cost an average of 2185.24 CHF (US$1750, £980, €1400). The average apartment price in Basel was 100.2% of the national average of 1116 CHF.^[50] The vacancy rate for the municipality, in 2010, was 0.74%.^[45]

Most of the population (as of 2000) speaks German (129,592 or 77.8%), with Italian being second most common (9,049 or 5.4%) and French being third (4,280 or 2.6%). There are 202 persons who speak Romansh.^[46]

From the 2000 census, 41,916 or 25.2% were Roman Catholic, while 39,180 or 23.5% belonged to the Swiss Reformed Church. Of the rest of the population, there were 4,567 members of an Orthodox church (or about 2.74% of the population), there were 459 individuals (or about 0.28% of the population) who belonged to the Christian Catholic Church, and there were 3,464 individuals (or about 2.08% of the population) who belonged to another Christian church. There were 12,368 individuals (or about 7.43% of the population) who were Islamic. There were 1,325 individuals (or about 0.80% of the population) who were Jewish, however only members of religious institutions are counted as such by the municipality, which makes the actual number of people of Jewish descent living in Basel considerably higher. There were 746 individuals who were Buddhist, 947 individuals who were Hindu and 485 individuals who belonged to another church. 52,321 (or about 31.41% of the population) belonged to no church, are agnostic or atheist, and 8,780 individuals (or about 5.27% of the population) did not answer the question.^[46]

Basel is subdivided into 19 quarters (Quartiere). The municipalities of Riehen and Bettingen, outside the city limits of Basel, are included in the canton of Basel-Stadt as rural quarters (Landquartiere).

Basel's airport is set up for airfreight; heavy goods reach the city and the heart of continental Europe from the North Sea by ship along the Rhine. The main European routes for the highway and railway transport of freight cross in Basel. The outstanding location benefits logistics corporations, which operate globally from Basel. Trading firms are traditionally well represented in the Basel Region.

Basel has Switzerland's only cargo port, through which goods pass along the navigable stretches of the Rhine and connect to ocean-going ships at the port of Rotterdam.

EuroAirport Basel Mulhouse Freiburg is operated jointly by two countries, France and Switzerland, although the airport is located completely on French soil. The airport itself is split into two architecturally independent sectors, one half serving the French side and the other half serving the Swiss side; prior to Schengen there was an immigration inspection point at the middle of the airport so that people could "emigrate" to the other side of the airport.

Basel has long held an important place as a rail hub. Three railway stations—those of the German, French and Swiss networks—lie within the city (although the Swiss (Basel SBB) and French (Bâle SNCF) stations are actually in the same complex, separated by Customs and Immigration facilities). Basel Badischer Bahnhof is on the opposite side of the city. Basel's local rail services are supplied by the Basel Regional S-Bahn. The largest goods railway complex of the country is located just outside the city, spanning the municipalities of Muttenz and Pratteln. The new highspeed ICE railway line from Karlsruhe to Basel was completed in 2008 while phase I of the TGV Rhin-Rhône line, opened in December 2011, has reduced travel time from Basel to Paris to about 3 hours.^[53]

Basel is located on the A3 motorway.

Within the city limits, five bridges connect Greater and Lesser Basel (downstream):

A somewhat anachronistic yet still widely used system of reaction ferry boats links the two shores. There are four ferries, each situated approximately midway between two bridges. Each is attached by a cable to a block that rides along another cable spanning the river at a height of 20 to 30 metres (66 to 98 feet). To cross the river, the ferryman orients the boat around 45° from the current so that the current pushes the boat across the river. This form of transportation is therefore completely hydraulically driven, requiring no outside energy source. [1] ^[134]

Basel has an extensive public transportation network serving the city and connecting to surrounding suburbs, including a large tram network. The green-colored local trams and buses are operated by the Basler Verkehrs-Betriebe (BVB). The yellow-colored buses and trams are operated by the Baselland Transport (BLT), and connect areas in the nearby half-canton of Baselland to central Basel. The BVB also shares commuter bus lines in cooperation with transit authorities in the neighboring Alsace region in France and Baden region in Germany. The Basel Regional S-Bahn, the commuter rail network connecting to suburbs surrounding the city, is jointly operated by SBB, SNCF and DB.

Basel is located at the meeting point of France, Germany and Switzerland; because it is so near other countries and is beyond the Jura Mountains, many within the Swiss military reportedly believe that the city is indefensible during wartime.^[54] It has numerous road and rail crossings between Switzerland and the other two countries. With Switzerland joining the Schengen Area on 12 December 2008, immigration checks were no longer carried out at the crossings. However, Switzerland did not join the European Union Customs Union (though it did join the EU Single Market) and customs checks are still conducted at or near the crossings.

Additionally there are many footpaths and cycle tracks crossing the border between Basel and Germany.

As the biggest town in the Northwest of Switzerland numerous public and private health centres are located in Basel. Among others the Universitätsspital Basel and the Universitätskinderspital Basel. The anthroposophical health institute Klinik-Arlesheim (formerly known as Lukas-Klinik and Ita-Wegman-Klinik) are both located in the Basel area as well. Private health centres include the Bethesda Spital and the Merian Iselin Klinik. Additionally the Swiss Tropical and Public Health Institute is located in Basel too.

Basel is at the forefront of a national vision to more than halve energy use in Switzerland by 2050. In order to research, develop and commercialise the technologies and techniques required for the country to become a 2000 Watt society, a number of projects have been set up since 2001 in the Basel metropolitan area. These include demonstration buildings constructed to Minergie or Passivhaus standards, electricity generation from renewable energy sources,^[56] and vehicles using natural gas, hydrogen and biogas.^[57] A building construction law was passed in 2002 also which stated that all new flat roofs must be greened leading to Basel becoming the world's leading green roof city. This was driven by an energy saving programme.^[58]

A hot dry rock geothermal energy project was cancelled in 2009 since it caused induced seismicity in Basel.

The city of Basel, located in the heart of the tri-border region (called Dreiländereck) is one of the most dynamic economic regions of Switzerland.

As of 2016, Basel had an unemployment rate of 3.7%.^[5] As of 2008, there were 18 people employed in the primary economic sector and about 9 businesses involved in this sector. 34,645 people were employed in the secondary sector and there were 1,176 businesses in this sector. 120,130 people were employed in the tertiary sector, with 8,908 businesses in this sector.^[45] There were 82,449 residents of the municipality who were employed in some capacity, of which females made up 46.2% of the workforce.

In 2008 the total number of full-time equivalent jobs was 130,988. The number of jobs in the primary sector was 13, of which 10 were in agriculture and 4 were in forestry or lumber production.

The over three dozen institutions yield an extraordinarily high density of museums compared to other cities of similar size and draw over one million visitors annually.^[84]
