Grimskär

Grimskär was an important part of the Swedish defense during the 17th Century and effectivly stopped the Danish fleet operating in the waters near Kalmar castle. During the 19th Century the fort was abandoned by the military but during WW II a top secret mine-station, controlling a line of anti-ship mines in the waters outside the city of Kalmar, was built under the old fort. The ferries between Kalmar and Öland passed over the line daily, the crews unaware of the mines. Not until 1988, when the mine-station was closed, the secret of it’s existence was revealed.
I pass Grimskär daily on my morning walk and usually take a picture or two of the old fort. Click on picture for a larger version.
