The Bunker Complex Ungerberg in Austria is a well-preserved military fortification from the Cold War era. Built to withstand prolonged attacks, the bunker features an impressive two and a half metre thick concrete encasement. Inside, visitors can explore a telephone exchange, a medical room, and even a niche for coffins, showcasing the comprehensive planning for long-term defense.
The complex also houses a decommissioned howitzer that remains in working order thanks to careful maintenance by the Museum of Military History.
