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.

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

By 1960 it had been sold by the War Office to Plymouth City Council.

The rear gorge has been filled in and now provides car parking.
