The Art Museum of the America’s is marking legendary modernist Brazilian architect Oscar Niemeyer’s 1ooth birthday with a retrospective of his career, which is still going strong.

The exhibit features original plans and sketches, video and photography footage and scale models of his major projects, including the U.N., which he designed with Le Corbusier, and the new capital city of Brasilia (pictured above), which was conceived and built in four years. It was completed and inaugurated in 1960.

Here’s a nice New York Times slideshow of some of Niemeyer’s major works.

The exhibit runs until Oct. 26.
