Round buildings

NOTES: The city of Brasilia was planned and developed in 1956 with Lucio Costa as chief urban planner and Oscar Niemeyer as principal architect. It formally became the capital of Brazil in 1960 and is the seat of all three branches of the Brazilian government. The National Congress buildings completed in 1958, comprise the Federal Senate, the Chamber of Deputies and the administrative twin Towers of Congress.

NOTES: This building comprises three independent types of structure: an in-situ reinforced concrete frame which holds together the main body of the cathedral; the sixteen load-bearing brick or concrete perimeter buildings, and the flat slab of the outdoor podium supported by concrete columns of load-bearing brick walls.

NOTES: In 1930 Sir Edwin Lutyens was commissioned to design the second Roman Catholic cathedral to contrast with the Gothic Revival Anglican cathedral of Giles Gilbert Scott being erected on the other end of Hope Street from 1904. Construction on Lutyens's massive structure began in 1933 but was suspended in 1941 due to wartime restrictions. Work recommenced on the crypt in 1956 and it was completed in 1958. Thereafter Lutyens's design was considered onerously expensive and was abandoned with only the crypt complete.
