This pleasingly wooded promontory fort is, according to Surrey Archaeological Society,"a roughly trapezoidal enclosure with the long axis lying north-east/south-west. The position of the earthworks is governed by the shape of the end of the ridge except where their north-eastern leg cuts perpendicularly across the length of the ridge. This north-eastern leg of the ramparts contains the entrance which is set off-centre towards the north-west, and has short out-turned banks on either side".
