A Brief History

Spitbank Fort: A Solent Sea Fortress

Rising from the waters of the Solent like a stone battleship, Spitbank Fort stands as one of Britain's most remarkable maritime defenses. This circular sea fort, located approximately one mile from Portsmouth Harbour, has witnessed over a century of transformation and stands ready to embark on an exciting new chapter.

Origins and Purpose

Spitbank Fort was commissioned in the 1860s as part of the Royal Commission on the Defence of the United Kingdom, established by Lord Palmerston following fears of French invasion under Napoleon III. These concerns led to the construction of an extensive network of fortifications around Portsmouth, earning them the nickname "Palmerston's Follies" from critics who deemed them unnecessary.

The fort was one of four sea forts built in the Solent – alongside Horse Sand Fort, No Man's Land Fort, and St Helen's Fort – designed to protect Portsmouth's vital naval dockyard from enemy warships. These innovative structures represented cutting-edge military engineering, built using granite blocks and positioned to create interlocking fields of fire across the Solent's shipping channels.
