The monument comprises a small sub-oval enclosure measuring approximately 13m N-S x 11m E-W externally and defined by low and spread stony banks, rising between 0.2 and 0.3m above the peaty exterior. It occupies level ground on a plateau to the SSW of the outcrop of Crugian Bach with wide views to the E and W. The bank is between 1.4 and 1.8m wide but is difficult to trace over much of its circumference due to its low relief against the surrounding grass. The only visible internal feature is a very faint in-turn of the bank for no more than 2.5m to the SSW. This may represent either an entrance or perhaps the remains of an internal structure as the enclosure is probably too large and irregular for a conventional hut circle. Alternative interpretations are offered by its location at the E edge of a cairn field containing both funerary and clearance cairns including one pair scheduled as BR375, and of the Crugian Bach Stone Circle 60m (BR274) to the E, along with several other possible cairns and standing stones beyond.

The monument is of national importance for its potential to enhance our knowledge of either prehistoric settlement and agriculture or funerary and ritual practices. Whilst unimpressive in itself, its importance lies in its form and context, being a distinctive element of a complex and diverse range of prehistoric monuments spread across the plateau to the E and W.

The scheduled area comprises the remains described and the area around them in which related evidence may be expected to survive. It is circular in shape and 20m in diameter.
