Cathedral of Brasília, Brazil

This Roman-Catholic church in Brazil’s capital was designed by Oscar Niemeyer to symbolize two hands pointing to heaven. The cathedral is made up of 16 concrete columns, representing hyperboloid structures with asymmetric sections. In the square outside the cathedral, four bronze sculptures representing the Evangelists greet visitors. Three suspended angel sculptures decorate the building’s interior, weighing 100 kg, 200 kg and 300 kg.
