Hubberston Fort was built between 1860 and 1865, and housed about 250 men in D-shaped, bomb-proof barracks which were defended at the landward side by a ditch protected by a counter-scarp gallery.
The casemated battery was situated further down the headland and originally comprised 28 guns. In the 1870s, eight of the guns on top of the casemates were removed and replaced by Moncrieff guns.

These guns were set on carriages and operated on a counterweight system so that they remained hidden in special concrete pits until the time came to fire them, when they would be hoisted into position; although partially in-filled with concrete for a 12-pdr QF practice battery these concrete pits are still visible. The casemates were bricked up early in the 20th century and the fort was abandoned shortly after WW1. In WW2 it was pressed into action as a communal air-raid shelter and as an American army camp, but it has since fallen into disrepair and has been so badly vandalised that visiting the fort is not advised. A small brick structure built over the east magazine and visible from the road is a WW2 mine-watching post.
