Unfinished part, U-boat base

Only the lower part of the north east defence was finished. The top gives a nice insight in the building process of a bunker. The lay out and outer walls are already there, only the roof had to be finished. Eventually this would be the same bunker as the finished corner, with an observation cupola and a Flak emplacement.

Steps to the observation room. The cupola would be put on the concrete bases.

Room inside the bunker.
