"On the summit of a prominent drumlin, the monument is a well preserved circular enclosure, 42.5m diam. The interior is level, but has been raised up to 1.2m above the surrounding ground. A substantial bank, measuring c.5m wide & up to 1.2m high encloses the site. There is a break in the bank on the E which probably marks the original entrance. The W half of the site is surrounded by a ditch c.5.5m wide, 2.5m below the interior & 0.6m below the outer ground level. A hedge boundary now surmounts the bank."
