Bembridge Fort is a fort built on the highest point of Bembridge Down close to the village of Bembridge on the Isle of Wight. It is one of the many Palmerston Forts built around Portsmouth during the period of the Second French Empire, as a safeguard against a perceived threat of French invasion by Napoleon III.
The hexagonally shaped fort was the main stronghold for the South East coastline of the Isle of Wight and was designed as a final retreat if the island was to be invaded. Due to its location with a view over both Sandown Bay and the Eastern Solent it acted as the command and control centre for the Western batteries on the Isle of Wight (Redcliff Battery, Yaverland Battery, Sandown Fort and Sandown Barrack Battery). The fort had barrack accommodation for 4 officers and 106 men with an original armament of six RBL 7 inch Armstrong guns mounted on the parapet side.
