The Niterói Contemporary Art Museum is situated in the city of Niterói, Rio de Janeiro, Brazil, and is one of the city’s main landmarks. It was completed in 1996.
Designed by Oscar Niemeyer with the assistance of structural engineer Bruno Contarini, who had worked with Niemeyer on earlier projects, the MAC-Niterói is 16 meters high; its cupola has a diameter of 50 meters with three floors. The museum has a collection of 1,217 works from the art collector João Sattamini. A collection assembled since the 1950s by that collector, constituted by the second largest collection of contemporary art in Brazil.
The museum projects itself over Boa Viagem beach and also a neighborhood, the 817 square metres reflecting pool that surrounds the cylindrical base “like a flower, ” in the words of Niemeyer.
A wide access slope leads to a Hall of Expositions, which has a capacity for sixty people. Two doors lead to the viewing gallery, through which can be seen Guanabara Bay, Rio de Janeiro, and Sugarloaf Mountain. The saucer-shaped modernist structure, which has been likened to a UFO, is set on a cliffside, at the bottom of which is a beach.
