Within Leigh Woods is Stokeleigh Camp, a hill fort thought to have been occupied from the third century BC to the first century AD and also in the Middle Ages. It is situated on a promontory, bounding the north flank of the Nightingale Valley and occupying around . Stokeleigh Camp is thought to have been occupied from the late pre-Roman Iron Age, when it was in the area controlled by the Dobunni. Archaeological investigations suggest during the 1st century Belgae tribes may have been present with some of the pottery showing the influence of the Durotriges. There may have been a break in occupation before reuse in the middle to late 2nd century. In addition to the pottery recovered a possible coin of Gallienus dating from his reign between 253 and 268 has been recovered. An iron-involuted brooch of the La Tène II type has also been found. It is unclear whether the occupation of Stokeleigh Camp in the 3rd century was for a formal garrison or whether it was just used by "squatters" or as a place of refuge in times of crisis. Stokeleigh might have been connected with the Wansdyke, a series of defensive linear earthworks, consisting of a ditch and an embankment running at least from Maes Knoll in Somerset, to the Savernake Forest near Marlborough in Wiltshire, however there is little evidence for this. It is also possible that the site was occupied in the Middle Ages.
