Forder Battery is a former 19th-century fort, built as a result of the Royal Commission on National Defence of 1859.

Part of an extensive scheme known as Palmerston Forts, after the prime minister who championed the scheme, it was built to defend the landward approaches to the north east of Plymouth, as an element of the plan for the defence of the Royal Naval Dockyard at Devonport.

Designed by Captain (later Maj General) Edmund Frederick Du Cane,[1] it was built by George Baker and Company and finished by the Royal Engineers.

[4] By the early 1900s the fort had become obsolete as a defensive position and was disarmed.

It was subsequently disposed of by the War Office, with much of the fort being redeveloped for housing.
