Fort Brockhurst is one of the Palmerston Forts, in Gosport, England. It is now an English Heritage property.
Fort Brockhurst was designed by William Crossman in the 19th century to protect Portsmouth. With its formidable firepower, its main purpose was to guard the approach from potential landing areas on the south Hampshire coast.
In August 1914 9th (Heavy) Battery Royal Garrison Artillery was formed at the Fort as part of the raising of Kitchener's New Army.
Although modern life has encroached on the fort, its fabric remains largely unaltered and the parade ground, gun ramps and moated keep can all be viewed. Constructional details of the casemates are able to be seen due to unrepaired second world war bomb damage at the North-East corner. The site is occasionally open to the public, under the auspices of English Heritage.
Fort Rowner to the South-West is in a similar state of preservation, but is inside HMS Sultan naval base and it is only opened to the public once a year under the banner of "Heritage Open Week".
