Burnham Beeches, a 374.6-hectare woodland near Farnham Common in Buckinghamshire, contains a slight univallate hillfort at Seven Ways Plain dating to the Late Bronze Age or Early Iron Age (c. 8th-5th century BC). The roughly oval enclosure measures 140 by 100 metres, enclosing 1.4 hectares on a broad plateau, and is defined by a single low rampart up to 5 metres wide surrounded by a ditch 10-15 metres wide. One of only about 150 such hillforts in England, it may have served as a stock enclosure, redistribution centre, or settlement. The wider site, owned by the Corporation of London since 1880, is a National Nature Reserve, SSSI, and Special Area of Conservation renowned for its ancient pollarded beech trees.
