The bunker is filled with items and relics from the battleship which met her fate outside Tromsø the 12th November 1944 when British bombers sunk her after a bombing raid where 971 of Tirpitz` crew lost their lives. The items is accompanied by lots of text and photos telling the story, and the guys running the museum is very knowledgeable and is happy to guide you and answer any questions. The museum can be visited every day during summer except Monday and Tuesday. Opening hours is from 1200 to 1700.
Outside the bunker you can visit the coastal fortification which still has two of the 10.5 cm gun positions intact with underground tunnels connecting them. There is also several other items spread out on the area, i.e a 200 cm searchlight and a rare 38 cm minethrower.
Across the road is another building with an exhibition, also filled with interesting items and photos, this exhibition is only open during the weekends though.
