In 1933 the Athens Charter, a manifesto of the modernist movement, was signed and was published later by Le Corbusier. Architects of this movement were among others: the Bauhaus-architect Ioannis Despotopoulos, Dimitris Pikionis, Patroklos Karantinos and Takis Zenetos. After World War II and the Greek civil war, the massive construction of condominiums in the major Greek city centres, was a major contributory factor for the Greek economy and the post-war recovery. The first skyscrapers were also constructed during the 1960s and 1970s, such as the OTE Tower and the Athens Tower Complex.
