Fort Gilkicker is a former 19th century Palmerston fort situated on the Hampshire coastline in Gosport, near Portsmouth. The fort was built between 1863 and 1871 with 22 casemates and equipped with five twelve-inch guns. The site fell into disuse in 1999, with several attempts to redevelop the site into apartments failing. The fort is a complete example of a Palmerston Fort.
