PHOTOS: Yugoslavia’s brutalist relics fascinate the Instagram generation

Genex Tower is unmissable on the highway from the Belgrade airport to the center of the city. Its two soaring blocks, connected by an aerial bridge and topped with a long-closed rotating restaurant resembling a space capsule, are such an unusual sight, the tower, built in 1977, has become a magnet for tourists despite years of neglect. The tower is one of the most significant examples of brutalism — an architectural style popular in the 1950s and 1960s, based on crude, block-like forms cast from concrete.
