Outside the city, Oxelösund in Sweden lies the Femore Fortress which provides a unique insight into the everyday life of the cold war and nowadays its open to visitors. Until 1997, the Fortress had the code name “Battery OD”, and here 70 people could stay for up to a month in the event of war.
Defense of the harbor entrance
The mounted 7.5 cm coastal artillery guns were built by Bofors in a 90-piece series. These had a range of 12.8 km and the firing rate was set to 25 shots per minute, which was sufficient enough to protect the entrance to Oxelösund harbor. Femöre was part of the block battalion “Bråviken” and was subject to Strängäs defense area.
Oxelösund is a very important harbor and in 1964 the fortress was ready. It was considered very modern and the domes under the fire pipes were able to resist a hit of easier nuclear charges. Even the gates into the mountain had shockwave protection.
Inside the mountain where the Femore Fortress is located, 70 people should stay in wartime. Since you could manage to stay there for up to a month, the place was set up as a small self-sufficient society. In total, the plant consisted of 3300 square meters, connected by a total of 450 meters long tunnels.
Electricity and water were well secured and an attack with chemical weapons was no big deal to handle.
Tales and myths about Femörefortet
Everything that is secret gives of course rise to persistent myths. Before the first public visit after the closure, it was discussed, among other things, that the island of Femöre had a bomb shelter for the entire population of Oxelösund, a submarine base, underground hospital or had tunnels to other islands in the archipelago.
The fort had been heavily modernized during the 1980s, including switching from optical sight to laser sight. In 1990 an exercise was held where the plant was further improved.
During the 1990s, the Cold War passed to the history books, and it was decided that the fortress would be demolished and replenished in 2003.
