History{{Further|Nordstern (city)}}BackgroundFollowing the occupation of Norway in 1940, it was soon realised that the country only had limited facilities for minor naval repairs. More extensive work usually meant a return to Germany. The capitulation of France two months later overshadowed the strategic importance of Norway to some extent, but it was still regarded as a better location for access to the Atlantic and Arctic Oceans than Germany. Nevertheless, better protection for U-boats from aerial attack was required so a bunker-building programme was instigated.[2] German U-boat bases in occupied Norway operated between 1940 and 1945, when the Kriegsmarine (German navy), converted several naval bases in Norway into submarine bases. Trondheim was an important U-boat base in Norway during the war. It was the home of the 13th flotilla and it had 55 U-boats assigned to the flotilla during its service.[3]ConstructionThe German civil and military engineering group, Organisation Todt, started constructing the facility as a submarine base as they were finishing Dora I (completed in June 1943).[4] Construction of Dora II began in 1942[2] but was never completed.[5] The second bunker was a little more than half complete by the time the war ended. If finished it would have been {{convert|168|ft|m}} long by {{convert|102|ft|m}} wide,[5] with four pens capable of holding six U-boats.[4] The completed walls are {{convert|3|m|ftin|abbr=on}} thick, and the roof is {{convert|3.5|m|ftin|abbr=on}} thick (only a quarter of the roof was completed).[6] After World War IIIn 1947 and 1948 the port authority conducted cleanup and blasting on Dora II. Part of the walls on the uncompleted sides were blasted away.[7] Dora II is used as a shipyard[4] and as a warehouse and garage for boats and cars by companies such as Trondheim Verft AS[8] and Skipsmaling AS.
