The Museum of Coastal Defence in Hel (Polish: Muzeum Obrony Wybrzeża) was established by the "Friends of Hel" society in buildings formerly occupied by the German "Schleswig-Holstein" 406 mm battery: the B2 gun emplacement and the range-finder tower. The Museum was opened to visitors on 1st May 2006. It is part of the Hel Museum Complex, which also includes the Hel Museum, the Museum of Hel Railways and the Laskowski battery stand on the Hel Peninsula. The main exhibition facility of the museum is the B-2 "Bruno" fire stand, which currently houses several permanent and temporary exhibitions, incl. Commander Zbigniew Przybyszewski's room (the commander of the peninsular battery named after H. Laskowski, patron of the museum), the exhibition "Marine Aviation Squadron in Puck", "32 days of Hel Defense", "War and Medicine" and the largest exhibition of grenades in Poland. In the forest nearby, a military open-air museum with cannons, mines, torpedoes and rolling stock was established. The aim of the museum is to show the military history of Hel and the Polish Navy.
