Rio Museum of Art

This guide to the Rio Museum of Art traces the building's earlier lives before it ever held art: the 1916 headquarters of the harbor engineers who fought Guanabara Bay's silt, and later the Mariano Procopio bus terminal that helped launch Rio's urban sprawl in the 1940s. You'll hear how the two structures sat forgotten for decades before a 2013 renovation joined them under one wave-shaped canopy. A good spot to notice the seam is where the old palace roofline meets the former terminal.
