This building is the Cathedral of Brasilia, constructed by Oscar Niemeyer in 1970. Niemeyer was a modern architect and that is evident throughout the structures that he designed. This Roman Catholic Cathedral is designed to be like a water tank with the sanctuary being underground. There is also a pool that surrounds the Cathedral that helps to keep the inside cool. Niemeyer favored the use of abstract shapes and curves over that of straight, perfectly clean lines. This is evident throughout a majority of the buildings designed by Niemeyer and can be clearly seen in the design above.
