This site is on the Holmen naval base and has the frigate Peder Skram, the motor torpedo boat Sehested and the submarine Sælen, all open for walk-through visits, along with the historic mast crane. It is described as Denmark's first Cold War museum. The frigate officially opened in 2008, and a working ship telephone system with a rotary dial is one of the details on board.
There are guided tours, a school service and events, and ships can be hired. Volunteers and supporter associations help run it. Holmen can only be reached on foot or by bicycle, and the nearest parking is at the Opera. The toilet is wheelchair accessible, but the entrance is not.
