Inside the rock and on the cliff top

Femörefortet (Battery OD) was built in the 1960s as a top-secret link in Sweden’s Cold War coastal defence. Inside the 450-metre rock tunnel lay command rooms, barracks, a kitchen and power generators designed to operate self-sufficiently for a month.

Today the fortress is run as a museum by the Femörefortet Association with guided tours, a museum shop and refreshments. Even when the underground tunnels are closed, visitors can walk freely across the headland among the gun turrets, radar tower and observation posts overlooking the shipping lane.
