In August 2004, in a closed-down barrack, the repairing and organizing works for the museum building began. Designed as a museum of naval technology, it displays aspects from the activity of the military harbor in Mangalia from 1952 to 2000. The Marine Museum Mangalia displays an impressive collection of navigation technology and heritage objects which give a truthful recent history of Military Marine, in two modern exhibition spaces and a library where objects from underwater weapons collection and section from torpedoes can be found. In the yard in front of the museum are exhibited pieces of a remarkable anti-aircraft artillery and naval collection, the main attraction being the cannon of 130 mm, which used to belong to the coast artillery.
