In what year was the National Congress completed?

The National Congress of Brazil, known for its distinctive modern architectural design, was completed in 1960. This landmark was designed by the renowned architect Oscar Niemeyer and reflects the principles of modernism characteristic of this period. Its construction was part of the broader initiative to develop the new capital city of Brasília, which was inaugurated in the same year. The National Congress serves as a symbol of the Brazilian government and features two towers flanked by a dome and a bowl, representing the legislative and executive branches respectively.

The other years listed do not align with the completion date of this iconic structure, as significant phases in Brasília's development occurred in the late 1950s, culminating with its official inauguration and the completion of major government buildings in 1960.
