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.
