[visited 10/1/03] Head into Thetford from the direction of the A1075 and you should go straight past this amazing earthwork. I took the road just before it and parked on the road just past it. This site is visually very rich though I believe most of the visible earthworks are Norman. The huge mound is very reminicent of Silbury Hill, though nowhere near as large. Plus this mound is surrounded by buildings and ramparts.
Watch out for the excessive mud in January as it makes climbing the Motte an “interesting” addition to the day.
