One of a number of forts built in the 1850s and 1860s to protect Portsmouth and its vital harbour against a French invasion. Largely unaltered, the parade ground, gun ramps and moated keep can all be viewed.
The fort currently stores a treasure trove of objects from English Heritage's extensive reserve collections.
Access on the second Saturday of the summer months is to the keep, armoury, washrooms, gun ramps and parade ground but does not include access to the curatorial stores.

Plan a Great Day Out
Continue your day with a visit to nearby Portchester Castle, for views across the Solent and a chance to browse the gift shop. Head into Portsmouth to visit the ornamental King James's and Landport Gates and the 13th century Royal Garrison Church, which was partially destroyed by bombing in 1941.
