Built in 1798 it was a self-contained triangular fort on a small scale, similar to the Dungeness batteries. The terreplein, slightly raised to give command of the sea, accommodated eight 24-pounders, and a brick loop-holed wall 3.5 metres high extended from the corners of the terreplein to form a sharp point at the rear. The main entrance, guardroom and ancillary buildings were spaced along the exterior walls. It was undermined by the sea by 1870 and washed away shortly after. No earthwork features were visible on the available historical aerial photographs but the fort is shown as an outline on the Ordnance Survey Map (1873-1881).
