Bangsbo Fort was built by the Germans during the Second World War, and known as StAtzpunktgruppe Frederikshavn SAd. In 1944 it was armed with 15 cm guns from the Danish Navy ship Niels Juel. During the Second World War the Germans built more than 70 concrete bunkers on the fort with 34 heavy and 17 light concrete bunkers and 30 other different concrete bunker systems. The fort belongs to the Danish Navy and since 2005 Nordjyllands Kystmuseum has rented large parts of the fort which is no longer in use, to tell the story about the fort.
