High and prominent partial contour hillfort high on the SE slopes of Table Mountain overlooking the River Usk and its confluence with the Grwyne Fawr and the confluence of Grwyne Fechan and Grwyne Fawr. Steep or very steep surrounding slopes, precipitous on E. Encloses area c. 100m NW-SE by 50m NE-SW with internal area 0.72ha. Around the plateau are the collapsed remains of a stone wall, on the S and SE a turfed stone bank and on the W and NE the crest is of loose stones. Rock-cut ditch can be seen in part. A strong counterscarp follows, the result of extensive ditch cleaning. Steeply inclined single inturned entrance on NE, with gap 1.75 m wide at the terminals of the inner rampart. Possible two hut depressions against the inside face of the inner wall on NW interior and round building to S of the entrance. To SW of the fort could be sites of structures of varying periods. On 1st Ed. OS map (1887). Minimal investigations, undated.
