Brasilia, Congress
Brazil's bicameral National Congress consists of Senate of Brazil and the Chamber of Deputies of Brazil. Since the 1960s, the National Congress has its seat in Brasilia. It was designed by Oscar Niemeyer following the style of modern Brazilian architecture. The semisphere to the left is the seat of the Senate, and the hemisphere to the right is the seat of the Chamber of the Deputies. Between them there are two towers of offices. The Congress also occupies other surrounding buildings, some of them interconnected by a tunnel. The building is located in the middle of the Monumental Axis, the city main street. In front of it there's a large lawn, where demonstrations take place.
