Trondheim - Dora

In 1941, the Germans began to build a submarine base called Dora I, which was completed in 1943. The base consisted of five pens that together could house seven submarines. In 1942 the construction of Dora II began, but this was never completed. The idea was that Dora II would consist of 4 pens with a total capacity of six submarines. The responsibility for the construction of both bases was Organisation Todt. When Dora I was ready, the base became the German 13th submarine flotilla’s main base. The flotilla consisted of about 55 submarines that were on assignment, while others were in port for maintenance and service. It was mainly the northern Atlantic and the Arctic Ocean that were the primary operating areas for submarines based in Norway. The goal was to sink allied convoys on their way to Murmansk and Arkhangelsk in the Soviet Union. The base was bombed at one point during the war but without any major damage being done.

My comment:

In what was Dora I lies among other things. Trondheim state archives, bowling alley, private firms and sports clubs. Dora II appears to be leased to private persons. It is fairly easy to walk around both Dora I and II. What makes Dora, in comparison with the submarine bases on the French Atlantic coast, less interesting is that they have been built on and that the old has partly disappeared in the new. It is rarely a successful combination to intervene in historic buildings, although in this case I understand the purpose.
