Priddy's Hard is an area of Gosport, in Hampshire, England now being developed for housing with part of the site retained as a museum. However, for some two hundred years it was a restricted-access site; first becoming a fort and then an armaments depot for Royal Navy and British Army weapons, explosives and other stores.
The oldest part of the site is now open to the public as the Explosion! Museum of Naval Firepower, which opened in 2001; in 2013 it became a constituent part of the National Museum of the Royal Navy. A new Millennium footbridge from Gosport town centre was constructed to aid the redevelopment and access to the area. New housing was built around parts of the original site, including an imitation of the early 19th-century Officers' Residence which faces the footbridge.
