Museu de Arte Contemporânea (MAC) The MAC contains over 10,000 works by Picasso, Matisse, Modigliani, Tarsila do Amaral, Portinari and Di Cavalcanti on its three sites. The largest and newest one is located in a huge Niemeyer building in front of Ibirapuera Park. There’s also a branch (this one) on the University of São Paulo campus in Cidade Universitária, and a smaller space inside the Bienal building, also in Ibirapuera, that showcases key Brazilian artists and movements.
