Femöre Coastal Artillery Battery, Cold War military museum in Oxelösund, Sweden.
Femöre Coastal Artillery Battery is a military museum in Oxelösund that displays an underground defense system from the Cold War era. The site contains over 450 meters of tunnels carved into solid granite, connecting underground chambers that include command centers and living quarters for personnel.
The battery was built in 1964 as part of Sweden's coastal defense network and was equipped with three 7.5 cm guns. It remained operational until 1997 and served as a key part of Swedish defense strategy against Soviet naval threats during the Cold War.
The site reflects how Sweden approached coastal defense during the Cold War and what daily life meant for those stationed here. Visitors can understand the role such fortifications played in the nation's security mindset and how communities understood the threat from across the sea.
Guided tours of the underground complex operate during summer months, with group visits available year-round by advance arrangement. Visitors should prepare for cool, damp conditions below ground and wear sturdy shoes, as walkways vary in surface quality.
The bomb-proof bunker was designed to accommodate up to 70 personnel with its own power generators and communication systems, allowing complete independence during wartime. This self-sufficiency reveals how seriously Sweden treated the potential threat and demonstrates how long the installation could operate without external support.
