U-boat base Kaseburg

In 1943, the German Navy (Kriegsmarine) built a port 3 km. south of Swinemünde in  present-day Poland.

The port served as a base for training cadets for submarines and S-boats [Schnell, known in England as E boats].  At the same time, the port was used for the supply and repair of ships. A narrow-track railway made it possible to transport torpedoes and ammunition from a depot in the forest up to the vessels.

Today, the port is only used by yachts and sailboats though some remains of workshops and barracks are scattered around the area.
