Although believed to be a Roman defensive work until as late as the early 1990s, carbon dating in 1996 of material recovered during a 1993 excavation revealed that this was actually a cursus, dating to 3600 BC.
The site is made up of a pair of ditches on either side of a central bank which runs for 1.8km. The bank varies from between 1m and 2m high and is between 8m and 1m wide (but spreading to 16m wide at the NW terminal), while the ditches – which are between 8m and 9m from the bank – vary in width up to 6.5m. A further 350m section is visible to the SE as a cropmark.
