Summary

W of Begbroke, located on a slightly raised plateau with good views. On 1st Ed. OS map (1885-1900). An oval enclosure of 2.5ha, approx. 200m N-S and 180m E-W. Bivallate with two ditches for its entire circuit, two possible entrances both simple gaps to the SE and NW. On the S the outer ditch is up to 8m wide, the outer bank 12m, the inner ditch 8m and the inner bank 6m. Excavation across one rampart and ditch (OUAS 1988) showed the rampart to be c6m wide with dry-stone revetting faces filled with rubble, sand and clay all of which showed burning. The site is now covered with trees and badly damaged especially at the N and W due to surface quarrying. Small amounts of pottery from the excavated ditch suggest an early Iron Age date.
