The bunker was designed to withstand a direct nuclear strike.
It served as one of the most secret and heavily fortified installations in the Swedish coastal defense system.
The base remained completely autonomous, featuring its own water wells, air filtration systems, and power generators.
The tunnels house a total of 3,300 square meters of space, much of it still containing original military technology.
The location was chosen for its strategic visibility over the shipping lanes leading to the Norrköping harbor.
During the Cold War, the fort was manned by a rotating crew of conscripts and professional officers kept in high readiness state.
Femörefortet is a decommissioned Cold War coastal artillery battery carved into the granite rock of the Femöre peninsula. The facility was constructed between 1962 and 1966 to monitor and defend the Baltic Sea approach to the Bråviken bay and Norrköping. It spans 3,300 square meters of tunnels and bunkers located 15 to 30 meters underground. The fort remained in active military readiness until its decommissioning in 1997. Today, it functions as a museum featuring original equipment, control rooms, and barracks preserved as they were during the Cold War. The site includes three 7.5 cm towers, although only one is fully restored for public viewing. Visitors explore the subterranean layout via guided or self-guided tours depending on the season. The complex highlights Sweden's defense strategy during the period of strict neutrality.

Bring a warm sweater or jacket as the temperature inside the rock tunnels remains low year-round.
Wear sturdy, closed-toe walking shoes to navigate the concrete flooring and occasional uneven surfaces.
Follow the designated paths closely to ensure you don't miss the smaller chambers like the radio and sonar rooms.
Do not wander off marked paths in the tunnels, as many areas remain closed for safety or structural reasons.
Primarily open during the summer months; generally closed during the winter season.
Maintain silence in sensitive equipment rooms and do not touch the preserved technical control panels.
