Dive into History
When these pages are complete (hopefully soon) then each of these boats will have its own "Dive" page with photos, maps, and contact information. Until then, the links simply link to the respective U-boat profiles.
Today I am not aware of any certain dive sites around Norway but several boats were sunk / scuttled in these waters including;
U-74 is a regular dive just off Cartagena, Spain. We do not know the depth at which she rests. There is a dive clud called "Puerto Almirante de Cabo de Palos" that dives the site on August 16, 1997.
(We need better information on this site, including position, depth, visibility and general conditions).
