Egg Buckland Keep is a former 19th-century fortified barracks, 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.

[2] It could accommodate 230 soldiers and provided storage for both shot and shell.

It was not designed to be armed, though five 7-inch Rifled Breech Loading guns were recommended in 1875, but never fitted.
