Depicted as a small circular shaped area with OD in centre marking spot height of 531 ft. OD on revised edition of the OS 6-inch map. Classified as a ring-barrow by O'Kelly (1944, 47) and described as following: 'A continuous rubble stone kerb 50' [15m] in overall diameter delineates this monument, which is situated on the highest point of Knockfennell. Its centre is a hollow bowl shape. It was excavated but the results were inconclusive, the only finds being pockets of cremated bone at various points round the kerb. There was no dating evidence. The excavation was directed by Dr. S. P. Ó Ríordáin'. The monument was described by Ó Ríordáin as a 'small cairn on hill-top' which he excavated in the 1940s (Ó Ríordáin 1954, 458). In 1978 the monument was described a ring-cairn situated on the summit of Knockfennell consisting of a ring-cairn of stones about 15m in diameter enclosing a hollow bowl shaped interior. Pockets of human bones were found amongst the orthostats (O'Kelly and O'Kelly 1978, 41).

Portal dolmen; likely dates to the Neolithic period (c. 4000–2500 BCE). Its location within a dense prehistoric landscape suggests it was part of a broader ritual or funerary complex associated with early farming communities in the region.
