The monument comprises the remains of three earthen built round barrows, which probably date to the Bronze Age (c. 2300 - 800 BC). The northern barrow is 20m in diameter and 2.5m high. It has an old trench, 4m long by 0.8m wide, in the centre, which was apparently dug in 1935 by Sir John C Lloyd of Brecon. The central barrow is 18m in diameter and 2m high, and also has a trench across the centre. The trench measures 4m long by 0.8m wide and was also dug by Sir John Lloyd in the 1920s. On the southern side of the barrow several large stones can be seen lying flat, which may be evidence of a kerb surrounding the barrow. The southern barrow measures 18m in diameter and 2m high and also has a trench cut into the top. The trench measures 3m long by 0.8m wide. Ridge and furrow abuts the western side of the barrow.

The monuments are of national importance for its potential to enhance our knowledge of prehistoric burial and ritual practices. The features are an important relic of a prehistoric funerary and ritual landscape and retain significant archaeological potential. There is a strong probability of the presence of both intact ritual and burial deposits, together with environmental and structural evidence. Barrows 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.
