The city of Athens contains a variety of different architectural styles, ranging from Greco-Roman, Neo-Classical, to modern. They are often to be found in the same areas, as Athens is not marked by a uniformity of architectural style. Many of the most prominent buildings of the city are either Greco-Roman or neo-classical in styling. Some of the neo-classical structures to be found are public buildings erected during the mid-nineteenth century, under the guidance of Theophil Freiherr von Hansen and Ernst Ziller, and include the Athens Academy, Athens City Hall, Greek Parliament, Old Parliament (1875-1932) (Now the National Historical Museum), University of Athens, and Zappeion Hall.
Modern architecture
Beginning in the 1930s, the International style and other architectural movements such as Bauhaus and Art Deco began to exert an influence on almost all Greek architects, and many buildings both public and private were constructed in accordance with these styles. Localities with a great number of such buildings include Kolonaki, and some areas of the centre of the city; neighbourhoods developed in this period include Kypseli.
In the 1950s and 1960s during the vast extension and development of Athens, modern architecture played a very important role. The centre of Athens was largely rebuilt, leading to the demolition of a number of neoclassical buildings. The architects of this era employed materials such as glass, marble and aluminium, while some blended modern and classical elements. After World War II, internationally known architects to have designed and built in the city included Walter Gropius, with his design for the US Embassy, and, amongst others, Eero Saarinen, in his postwar design for the east terminal of the Ellinikon Airport.
Notable Greek architects of the 1930s-1960s included Konstantinos Doxiadis, Dimitris Pikionis, Pericles A. Sakellarios, Aris Konstantinidis and others.
