Cathedral of Brasília

The Cathedral of Brasília (Catedral Metropolitana Nossa Senhora Aparecida) is the Roman Catholic cathedral serving Brasília, Brazil, and serves as the seat of the Archdiocese of Brasília. It was designed by Oscar Niemeyer, and was completed and dedicated on May 31, 1970. The cathedral is a hyperboloid structure constructed from 16 concrete columns, weighing 90 tons each.

The exterior of the cathedral resembles the circular plan and ribbed structure of Liverpool Metropolitan Cathedral, but the latter is clad in solid material, while the Cathedral of Brasília allows light in and out for almost the full height of the ribs.

The Cathedral of Brasilia, officially the Metropolitan Cathedral of Our Lady Aparecida (Catedral Metropolitana Nossa Senhora Aparecida), dedicated to the Blessed Virgin Mary under her title of Our Lady of Aparecida, proclaimed by the Church as Queen and Patroness of Brazil, is an expression of the architect Oscar Niemeyer.
