Architecture of Turkey or Turkish architecture in the republican period is the architecture practised in Turkey since the foundation of the republic in 1923. In the first years of the republic, Turkish architecture was influenced by Seljuk and Ottoman architecture, in particular during the First National Architectural Movement (also called the Turkish Neoclassical architecture movement). However, starting from the 1930s, architectural styles began to differ from traditional architecture, also as a result of an increasing number of foreign architects being invited to work in the country, mostly from Germany and Austria. The Second World War was a period of isolation, during which the Second National Architectural Movement emerged. Similar to Fascist architecture, the movement aimed to create a modern but nationalistic architecture.
From the 1950s the nation became more internationally connected, which enabled Turkish architects to experiment with new styles and become increasingly inspired by their counterparts in the rest of the world. However, they were largely constrained by the lack of technological infrastructure or insufficient financial resources until the 1980s. Thereafter, the liberalization of the economy and the shift towards export-led growth paved the way for the private sector to become the leading influence on architecture in Turkey.
1920s to early 1930s: First national architectural movement
The First National Architectural Movement (Turkish: Birinci Ulusal Mimarlık Akımı) was an architectural movement led by Turkish architects Vedat Tek (1873–1942) and Mimar Kemaleddin Bey (1870–1927). Followers of the movement wanted to create a new and "national" architecture, which was based on motifs from Seljuk and Ottoman architecture. The movement was also labelled Turkish Neoclassical architecture, or the National Architectural Renaissance. Other prominent followers of this movement were Arif Hikmet Koyunoğlu (1888–1982) and Giulio Mongeri (1873–1953). Notable buildings from this era are the Istanbul Main Post Office (1905–1909), Tayyare Apartments (1919–1922), Istanbul 4th Vakıf Han (1911–1926), State Art and Sculpture Museum (1927–1930), Ethnography Museum of Ankara (1925–1928), Bebek Mosque, and Kamer Hatun Mosque.
Italian architect Raimondo D'Aronco served as the chief palace architect to the Ottoman Sultan Abdülhamid II in Istanbul for 16 years. D'Aronco designed and built a large number of buildings of various types in Istanbul. The stylistic features of his works can be classified in three groups: Revivalism, reinterpretation of the Ottoman forms, Art Nouveau and Vienna Secession. Art Nouveau was first introduced to Istanbul by D'Aronco, and his designs reveal that he drew freely on Byzantine and Ottoman decorations. D'Aronco also mixed Western and Oriental styles in his work, which was likewise a notable characteristic of the designs of Alexander Vallaury in the same period.
1930s to 1950s: Modernism and foreign influence
The Bauhaus style Florya Atatürk Marine Mansion (1935) and the Art Deco style Ankara Central Station (1937) are among the notable examples of this era. As there were not enough architects in Turkey until the 1950s, various architects were invited by the government from Germany, Austria, Switzerland and France, in order to manage the rapid construction of the new capital Ankara. About 40 architects and urban planners designed and oversaw various projects (mostly in Ankara, and to a lesser extent in Istanbul and Izmir) between 1924 and 1942. Among them were Gudrun Baudisch, Rudolf Belling, Paul Bonatz, Ernst Arnold Egli, Martin Elsaesser, Anton Hanak, Franz Hillinger, Clemens Holzmeister, Henri Prost, Paolo Vietti-Violi, Werner Issel, Hermann Jansen, Theodor Jost, Heinrich Krippel, Carl Christoph Lörcher, Robert Oerley, Bernhard Pfau, Bruno Taut and Josef Thorak.
Selected examples of buildings from this era are the Bauhaus style Florya Atatürk Marine Mansion (1935) designed by Seyfi Arkan; the Art Deco style Ankara railway station (1937) designed by Şekip Akalın; the Court of Cassation building (1933–35) designed by Clemens Holzmeister; the Faculty of Languages, History and Geography building (1937) of Ankara University designed by Bruno Taut; and the Grand National Assembly of Turkey building (1938–63) designed by Clemens Holzmeister.
