The Royal Norwegian Navy Museum (Marinemuseet in Norwegian) is a museum documenting the history of the Royal Norwegian Navy. It is located at the former main naval base of Karljohansvern in Horten. The museum was founded by C.F. Klinck on 24 August 1853. The museum is sometimes regarded as the world's first naval museum, as it was the first collection of naval memorabilia open to the public.
