Tito's Bunker, also known as the Atomic War Command (ARK), is a massive underground military complex located near Konjic in Bosnia and Herzegovina. Built between 1953 and 1979 during the Cold War era, this secret facility was designed to serve as a nuclear shelter and command center for Yugoslav President Josip Broz Tito and the country's political and military leadership in case of atomic war. The bunker extends 280 meters into the mountainside and features over 6,500 square meters of space spread across multiple levels.
The facility was constructed in extreme secrecy, with workers sworn to silence and the project disguised as a mine or other civilian construction. Inside, the bunker contains residential quarters, conference rooms, offices, and even Tito's private apartment, all preserved in their original state. In June 2014, the bunker was declared a national heritage monument and placed on the list of protected Cultural and Historical Monuments of Bosnia and Herzegovina by the Commission to Preserve National Monuments.
