Lyneham camp is four miles from Chipping Norton, located 650 feet above sea level on a ridge commanding a fine view all round except to the north. It is roughly circular covering about four and a half acres. A single rampart surrounds the camp and is about five feet high in some places. There is a gap in the ramparts to the north – a possible original entrance. The camp was surrounded by a ditch, but this is barely visible now. A quarry has been cut into the south end.
Excavations were carried out by the Oxford University Archaeological Society in June 1956. Iron Age pot sherds and a bone needle were amongst the small number of finds. The camp is known locally as Lyneham ‘Roundabout’ and is a scheduled ancient monument. In the 19th century skeletons were discovered in the south side of the hillfort (the quarry site).
