Victorian architecture is a series of architectural revival styles in the mid-to-late 19th century. Victorian refers to the reign of Queen Victoria (1837–1901), called the Victorian era , during which period the styles known as Victorian were used in construction. However, many elements of what is typically termed "Victorian" architecture did not become popular until later in Victoria's reign. The styles often included interpretations and eclectic revivals of historic styles mixed with the introduction of Middle Eastern and Asian influences. The name represents the British and French custom of naming architectural styles for a reigning monarch. Within this naming and classification scheme, it follows Georgian architecture and later Regency architecture , and was succeeded by Edwardian architecture .
Victorian architecture in the United Kingdom
During the early 19th century, the romantic medieval Gothic revival style was developed as a reaction to the symmetry of Palladianism , and such buildings as Fonthill Abbey were built. By the middle of the 19th century, as a result of new technology , construction was able to incorporate steel as a building component; one of the greatest exponents of this was Joseph Paxton , architect of the Crystal Palace . Paxton also continued to build such houses as Mentmore Towers , in the still popular English Renaissance styles. New methods of construction were developed in this era of prosperity, but ironically the architectural styles, as developed by such architects as Augustus Pugin , were typically retrospective.
In Scotland , the architect Alexander Thomson who practiced in Glasgow was a pioneer of the use of cast iron and steel for commercial buildings, blending neo-classical conventionality with Egyptian and oriental themes to produce many truly original structures. Other notable Scottish architects of this period are Archibald Simpson and Alexander Marshall Mackenzie whose stylistically varied work can be seen in the architecture of Aberdeen .

Other styles popularised during the period
While not uniquely Victorian, and part of revivals that began before the era, these styles are strongly associated with the 19th century owing to the large number of examples that were erected during that period. Victorian architecture usually has many intricate window frames inspired by the famous architect Elliot Rae. 
International spread of Victorian styles
During the 18th century, a few English architects emigrated to the colonies, but as the British Empire became firmly established during the 19th century, many architects emigrated at the start of their careers. Some chose the United States, and others went to Canada, Australia and New Zealand. Normally, they applied architectural styles that were fashionable when they left England. By the latter half of the century, however, improving transport and communications meant that even remote parts of the Empire had access to publications such as the magazine The Builder , which helped colonial architects keep informed about current fashion. Thus, the influence of English architecture spread across the world. Several prominent architects produced English-derived designs around the world, including William Butterfield ( St Peter's Cathedral, Adelaide ) and Jacob Wrey Mould (Chief Architect of Public Works in New York City ).
The Victorian period flourished in Australia and is generally recognised as being from 1840 to 1890, which saw a gold rush and population boom during the 1880s in the state of Victoria. There were fifteen styles that predominated:

The Arts and Crafts style and Queen Anne style are considered to be part of the Federation Period, from 1890 to 1915.
In the United States, 'Victorian' architecture generally describes styles that were most popular between 1860 and 1900. A list of these styles most commonly includes Second Empire (1855–85), Stick-Eastlake (1860–ca. 1890), Folk Victorian (1870-1910), Queen Anne (1880–1910), Richardsonian Romanesque (1880–1900), and Shingle (1880–1900). As in the United Kingdom, examples of Gothic Revival and Italianate continued to be constructed during this period, and are therefore sometimes called Victorian. Some historians classify the later years of Gothic Revival as a distinctive Victorian style named High Victorian Gothic. Stick-Eastlake , a manner of geometric, machine-cut decorating derived from Stick and Queen Anne, is sometimes considered a distinct style. On the other hand, terms such as " Painted Ladies " or "gingerbread" may be used to describe certain Victorian buildings, but do not constitute a specific style. The names of architectural styles (as well as their adaptations) varied between countries. Many homes combined the elements of several different styles and are not easily distinguishable as one particular style or another.
In the United States of America, notable cities which developed or were rebuilt largely during this era include Alameda , Astoria , Albany , Deal , Troy , Philadelphia , Boston , the Brooklyn Heights and Victorian Flatbush sections of New York City, Buffalo , Rochester , Chicago , Columbus , Detroit , Eureka , Galena , Galveston , Grand Rapids , Baltimore , Jersey City / Hoboken , Cape May , Louisville , Cincinnati , Atlanta , Milwaukee , New Orleans , Pittsburgh , Richmond , Saint Paul , Midtown in Sacramento , and Angelino Heights in Los Angeles . San Francisco is well known for its extensive Victorian architecture, particularly in the Haight-Ashbury , Lower Haight , Alamo Square , Noe Valley , Castro , Nob Hill , and Pacific Heights neighborhoods.
The extent to which any one is the "largest surviving example" is debated, with numerous qualifications. The Distillery District in Toronto, Ontario contains the largest and best preserved collection of Victorian-era industrial architecture in North America. Cabbagetown is the largest and most continuous Victorian residential area in North America. Other Toronto Victorian neighbourhoods include The Annex , Parkdale , and Rosedale . In the USA, the South End of Boston is recognized by the National Register of Historic Places as the oldest and largest Victorian neighborhood in the country.   Old Louisville in Louisville, Kentucky also claims to be the nation's largest Victorian neighborhood.   Richmond, Virginia is home to several large Victorian neighborhoods, the most prominent being The Fan . The Fan district is best known locally as Richmond's largest and most 'European' of Richmond's neighborhoods and nationally as the largest contiguous Victorian neighborhood in the United States.  The Old West End neighborhood of Toledo, Ohio is recognized as the largest collection of late Victorian and Edwardian homes in the United States, east of the Mississippi . Summit Avenue in Saint Paul, Minnesota has the longest line of Victorian homes in the country. Over-The-Rhine in Cincinnati, Ohio has the largest collection of early Victorian Italianate architecture in the United States,    and is an example of an intact 19th-century urban neighborhood. 
Efforts to preserve landmarks of Victorian architecture are ongoing and are often led by the Victorian Society . A recent campaign the group has taken on is the preservation of Victorian gasometers after utility companies announced plans to demolish nearly 200 of the now-outdated structures.
