Hanstholm Fortress

Hanstholm fortress was a large coastal fortification, built by Nazi Germany at Hanstholm in north-western Denmark during World War II. The remains of the fortress is now a World War II museum situated in Thy National Park.Hanstholm Fortress was part of the "Atlantic Wall" and its main purpose was to seal off the entrance to Skagerrak together with the Vara fortress in Kristiansand, southern Norway, and extensive minefields in Skagerrak. The fortress had a wide range of artillery, from medium-sized 17 cm SK L/40 guns up to four 38 cm S.K.C/34 guns, weighing 110 tons each . The guns were protected by 3.5 metres of reinforced concrete and many anti-aircraft guns. The 38 cm guns were similar to the ones fitted to the Bismarck-class battleships and had been intended for the battleships Scharnhorst and Gneisenau. However, after Gneisenau was damaged in a bomb raid, a decision was made not to fit the guns to the ship, but to use them instead in fortresses. The guns could fire a 495-kilogram projectile 55 kilometres , or an 800 kg shell 42 km . The rate of fire was 1 shot per 1.5 minutes. The fortress was defended by German Naval Artillery Battalion 118.
