The monument comprises a prehistoric monument complex containing the remains of five round cairns; burial mounds, and a standing stone, probably dating to the Bronze Age (c.2300 BC - 800 BC) and situated at the end of a low ridge at the foot of Tyle Ddu. The eastern edge of the complex is marked by a standing stone which measures 2m high, 1.3m wide and is 0.4m deep. At 15m to the west north west is a cairn measuring 15m in diameter and 1.5m high with an exposed cist in the centre and evidence of a kerb on the south west side. Another 60m along this alignment is a second cairn measuring 8m in diameter and 0.4m high with traces of a kerb on the east side. Of the remaining cairns two are located 100msouth west and one 270m north west of this central group. The outlying cairn north western cairn measures 6m in diameter and is 1m high; whilst to the south west the northern cairn measures 11m in diameter and is 0.4m high and the southern, situated 30m south west of the first, measures 11m in diameter and is 0.4m high.

The monument is of national importance for its potential to enhance our knowledge of prehistoric burial and ritual practices. The features are important relics of a prehistoric funerary and ritual landscape and retain significant archaeological potential, with a strong probability of the presence of both intact burial or ritual deposits and environmental and structural evidence. Cairnfields may be part of a larger cluster of monuments and their importance can further enhanced by their group value.

The scheduled area comprises the remains described and areas around them within which related evidence may be expected to survive.
