El contacto entre el espacio moderno y el paisaje suramericano: Le Corbusier en 1929 The contact between modern space and the South American landscape:

During his first visit to South America in 1929 Le Corbusier outlined his urban plans for Buenos Aires, Montevideo, Sao Paulo and Rio de Janeiro. Designed over seventy-four days in the southern hemisphere the sketches showed the transformation of the idea that the architect had been working on since 1925: his Voisin Plan for Paris. This was the building of cruciform towers on platforms that were artificially placed on pre-existing structures in order to make winding landscape megastructures on an abrupt and unchanged landscape. New horizons were opened: for his work as well as for modern Brazilian architecture.
