Barkhale Camp causewayed enclosure

Barkhale Camp is a Neolithic causewayed enclosure, an archaeological site on Bignor Hill, on the South Downs in West Sussex, England. Causewayed enclosures were built in England from shortly before 3700 BC until at least 3500 BC; they are characterized by the full or partial enclosure of an area with ditches that are interrupted by gaps, or causeways. Their purpose is not known; they may have been settlements, meeting places, or ritual sites. The Barkhale Camp enclosure was first identified in 1929, by John Ryle, and was surveyed the following year by E. Cecil Curwen, who listed it as a possible Neolithic site in a 1930 paper which was the first attempt to list all the causewayed enclosures in England. A small trench was dug in 1930 by Ryle, and a more extensive excavation was undertaken by Veronica Seton-Williams between 1958 and 1961, which confirmed Curwen's survey and found a characteristically Neolithic assemblage of flints. Peter Leach conducted another excavation before the southern part of the site was cleared of trees in 1978, examining several mounds within the enclosure, and attempting to determine the line of the ditch and bank along the southern boundary. No material suitable for radiocarbon dating was recovered, which meant that dating the site was not possible with any precision, but Leach suggested that the site had been constructed in the earlier Neolithic, between 4000 BC and 3300 BC. The site is owned by the National Trust. It has been protected as a scheduled monument since 1967.
