Collection on the development of radio and sea signal technology. The lightship was built between 1914 and 1918 at the Meyer shipyard in Papenburg. The lightship was tirelessly in service in the German Bight for 65 years, showing the way for seafaring. Since August 2, 1984, the Deutsche Bucht has been moored in the Emder Ratsdelft. Today, the ship is a maritime history museum. Of particular interest is the oldest intact lightship engine. In addition, there is a very cozy and maritime cabin restaurant and a registry office of the city of Emden on board.
