Situated NW of Cobham, on the crest of a prominent hill overlooking the valleys of the Thames, Wey and Mole rivers. Irregularly shaped, damaged by several roads crossing the site and buildings within it. Generally univallate with an outer ditch and counterscarp bank enclosing 5.5ha. To the W, however, where the natural slope is less there are three banks and two ditches and to the NE is a D-shaped annex with an additional bank which encloses a stream. To the SW the earthworks cut off 3 spurs of the hill. The main inner rampart survives up to 10m wide and 2.2m high with the ditch up to 7m wide in places and up to 4m below the rampart, this is completely infilled in stretches and visible as a terrace c.3m wide. The counterscarp bank is up to 10m wide and 1m high. The additional works to the W include a second ditch now infilled and 3m wide and two extra banks, one 7m wide and 0.3m high and the other 12m wide and 2,2m high. The annex is defined by a single bank, up to 8m wide and 1.8m high, and an outer ditch 7m wide and 2m deep. The entrance through the main inner rampart is a simple gap into the annex, the terminal ends of the rampart are increased in height and width. A section of bank runs from the entrance and out from the annex, this may be associated with an ancient trackway. Excavations through the rampart and ditch in 1911 (Gardner) showed the site to be Iron Age, the building of houses in the SW sector revealed early, middle and late Iron Age pottery and iron working slag. Further excavations in 1981 (Poulton and O'Connell) showed that the ramparts were of two phases, the earlier one collapsing, and that the annex could have been a second phase addition. A watching brief in 1973 suggested a possible second ditch in the SE (Bird (1973). There are early plans of the site by Manning and Bray (1804) and Downman (1889), it is on the 1st Ed OS map (1885-1900).
