Fort Grange is one of the Palmerston Forts, in Gosport, England. After Gomer and Elson forts had been approved in 1852, further consideration led to a decision to fill the gap between them by three more forts, and Grange is the most southerly of the three. Work began in 1858 and it was completed in 1863. Built as part of the outer defence line for Gosport along with Fort Brockhurst, Fort Elson and Fort Rowner to the North East and Fort Gomer to the South West.
