The National Monuments Service's description

In pasture, located at the N end of a low N–S ridge. The rath straddles the narrow top of the ridge, utilising the steeply sloping W slope.
Raised circular area (26.4m N–S; 26.9m E–W) defined by a scarp, and enclosed E–NNW by a fosse with traces of an external bank. The enclosing scarp (ext. H 2.3m at NNE; 1.8m at SW, 3.4m at W; Wth slope c. 4.5-6.5m) is enhanced by the natural fall of ground. It retains a slightly raised internal rim, with remnants of a stone kerb evident in parts at SSE–SSW. Stones protrude randomly from the external face of the scarp. A short semi-circular section of the enclosing scarp has been quarried out at the N.
The fosse (Wth 3.4m; D 0.4-0.8m) is evident as a shallow depression ESE–S, best defined at SSE-S where it cuts across the spine of the ridge; at SW–NW, where it coincides with the steep ridge slope, it changes to a terrace (Wth 2-2.5m) with an external stony scarp (H 1m) cut into the natural slope; the terrace terminates at N. The fosse is not evident at N–NE, and is overlain by a later roughly N–S field fence at E.
There is a possible external bank, evident as a low, sod-covered stony rim (Wth 2-2.4m), on the outer edge of the fosse at ESE–SW.
The interior is highest at SW, sloping down gently from there to NE. At the E a poorly defined, slumped gap (Wth c. 2m) appears to mark the original entrance; a slight rise in ground level outside the gap may mark the remnants of access ramp or causeway. Immediately inside the entrance, on the S side, a shallow, oblong depression (8.4m NE–SW; 4.5m NW–SE; D 0.4m) extends to the SE into the interior. The rath is ringed with hazel scrub. There is an enclosure (MA038-115----) located 20m to N.
