Cathedral of Brasilia (Brazil)

The Cathedral of Brasília (Catedral Metropolitana Nossa Senhora Aparecida) is a breathtaking building that serves as the seat for the Archdiocese of Brasília. The Roman Catholic cathedral was designed by Oscar Niemeyer, and although the keystone was first placed in 1958 it was not completed and dedicated until May 31, 1970.

The cathedral is said to have been influenced by the Liverpool Metropolitan Cathedral, as it is similar in design but instead of solid material the Cathedral de Brasilia allows light in to illuminate the building from top to the bottom with natural light giving a much more spiritual experience. The building is complimented with sculptures representing the evangelists that were created by Dante Croce.
