Museu Colecçao Berardo

The private modern-art collection of millionaire José Berardo is a trippy Pop art journey encompassing nearly every contemporary art movement since Cubism. Lichtenstein, Warhol, and Pollack are all here in the 900-plus-piece collection representing 70 artistic tendencies. It is the highlight of Centro Cultural de Belém, a cultural megacomplex in Belém. The best part? Entrance is free.
