Explosion — the Museum of Naval Firepower — occupies Priddy's Hard, a former Royal Navy armaments depot on the western shore of Gosport harbour. The site stored and maintained naval ordnance for over 200 years, and the history of that work — from black powder in the age of sail to guided missiles — is told through a large collection of weapons, fuses, shells, torpedoes, and mines.
The museum is particularly strong on the human stories: the workers (many of them women) who filled shells by hand during both World Wars, the engineers who maintained the weapons, and the sailors who used them. The setting itself is historically remarkable — the Georgian magazine buildings, the Camber, the powder-proof walls — and gives the exhibits a physical authority. The outdoor area has a collection of full-size naval guns and missiles.
