A Niemeyer creation, the Memorial da América Latina is like a mini-Brasília, with a series of glass-and-cement structures in a beautiful if unsettling variety of shapes and sizes. While it looks uninviting at first glance, the sprawling complex has undergone renovations to make it more welcoming – and interesting – to visitors. The Salão dos Atos is a ceremonial space where you can see Cândido Portinari’s enormous painting Tiradentes. The perfectly round Galeria Marta Traba de Arte Latino-Americano displays contemporary art from around Latin America. And the Pavilhão de Criatividade displays a diverse collection of Latin American arts and crafts.
