Maritiman is a floating maritime museum in Gothenburg harbour, made up of around a dozen historic vessels moored together, including a naval destroyer, a submarine, lightships and tugs. Visitors walk between the ships to explore engine rooms, crew quarters and decks. Admission is ticketed, and the open-air museum on the water offers an engaging look at Gothenburg strong seafaring and shipbuilding heritage beside the Lilla Bommen waterfront.
