At the end of the second World War the German military blew up the central part the fort. Since 1979 the Lithuanian sea museum uses the fort after the reconstruction. The reconstructed central part of the fort houses aquariums with fish species from Lithuania's fresh waters, the Baltic Sea and tropic seas, as well as a permanent display of prepared samples of marine fauna. Penguins, Baltic Sea seals and Steller's Sea lions live in the outdoor pools next to the aquarium building.
