Karl-Marx-Allee is a monumental socialist boulevard built by the GDR between 1952 and 1960 in Berlin Friedrichshain and Mitte. Today the boulevard is named after Karl Marx. It should not be confused with the Karl-Marx-Straße in the Neukölln district of Berlin.
The boulevard was named Stalinallee between 1949 and 1961, and was a flagship building project of East Germany's reconstruction programme after World War II. It was designed by the architects Hermann Henselmann, Hartmann, Hopp, Leucht, Paulick, and Souradny to contain spacious and luxurious apartments for workers, as well as shops, restaurants, cafés, a tourist hotel, and an enormous cinema, the Kino International.
The avenue, which is 89 metres wide and nearly 2 kilometres long, is lined with monumental eight-story buildings designed in the wedding-cake style, the socialist classicism of the Soviet Union. At each end are dual towers at Frankfurter Tor and Strausberger Platz designed by Hermann Henselmann. The buildings differ in the revetments of the facades which contain often equally, traditional Berlin motifs by Karl Friedrich Schinkel. Most of the buildings are covered by architectural ceramics.
