The National Monuments Service's description
On a slight rise in a low-lying landscape with a SW-NE stream immediately to the NW. Circular grass-covered area (diam. 46m N-S; 42m E-W) defined by an earthen bank (Wth 3-3.4m; int. H 0.35m; ext. H 0.7-1.3m) which is reduced to a scarp (H 1.4m) NW-N, and a rounded fosse (Wth of top 5.7-7m; Wth of base 2.7-3.5m; D 0.1-0.3m) N-S-WNW. The entrance (Wth 2m) is at SSE.
It is within a D-shaped enclosure (dims c. 180m NE-SW; c. 100m NW-SE) defined by an earthen bank which is best preserved (Wth 3.3m; int. H 0.5m; ext. H 0.75m) at E and which is reduced to a scarp (H0.1-0.2m) SSW-W, with traces of an outer fosse (Wth of base 1.6m; D 0.1m) NE-SSW. The outer enclosure backs onto the channeled stream at NW and cannot be seen beyond it where a coniferous forest had been planted by 2005 (OSAP).
