One of the few U-boat pens on German territory to survive the WW2, the Island of Heligoland was later used as a bomb target for the RAF and the bunker was largely destroyed. When civilians were allowed to return to the island, the area was used for the building and repair of boats. In recent years an Oceanographic Institute has been built on the ruins and the only identifiable remains is the quayside immediately outside Dock 1 on the right of the model photograph.
Noordsee III is modelled here during the war soon after completion with AA guns on the roof and minimal weathering.
