The National Monuments Service's description
In hilly undulating pasture, incorporating a natural hillock with excellent views.
Not shown on the 1838 OS 6-inch map; shown on the 1916 edition as a wooded subcircular enclosure.
An earthen bank/scarp (Wth 2m; int. H 0.3m; ext. H 1.2m at SW), ringed with mature beech and ash trees and some scrub, encloses the top and steep N-facing slope of a hillock. The enclosed subcircular space (diam. c. 50-55m) has an oblong flattish area in the centre from which ground falls steeply to NW, N and NE. Three quarry pits (10-15m across) cut deeply into the N, E and S slopes. At N the base of the hillock is incorporated into an E−W field fence. The interior is grassy with clumps of brambles and overgrowth and a few hawthorn and ash trees.
