Museum of Contemporary Art, Belgrade

This modernist museum stands at the confluence of the Sava and Danube in New Belgrade, its crystalline volumes of white marble and glass a landmark of postwar architecture. Opened in the 1960s, it holds one of the region's most important collections of twentieth-century Yugoslav art, spanning painting, sculpture, and new media. Terraced galleries step around a central atrium filled with daylight. After a lengthy reconstruction, the building reopened to display avant-garde and contemporary work in a setting as significant as the art it houses.
