On the former naval base of Holmen in Copenhagen, rows of gun boat sheds line the island of Frederiksholm. These where used for storing the canon boats used during the so-called Gun Boat War, 1807 - 1814 between Denmark-Norway and the UK. The use of gun boats on the Danish side was a necessity after the English had stolen the fleet after the bombardment of Copenhagen in 1807. Today the protected sheds are being converted into offices for mainly IT companies and architects.
