Tito’s Bunker, officially known as the Atomic War Command, is a massive underground complex hidden beneath the hills of Konjic, Bosnia and Herzegovina. Built in secret during the Cold War, it was designed to shelter President Josip Broz Tito and his top officials in case of a nuclear attack. Covering over 6,500 square meters with more than 100 rooms, the bunker remains astonishingly well-preserved and today serves as both a historical site and a contemporary art venue.
