The monument comprises the remains of two chambered tombs, dating to the Neolithic period (c. 4,400 BC - 2,900 BC). Chambered tombs were built and used by local farming communities over long periods of time. There appear to be many regional traditions and variations in shape and construction.

The two burial chambers are known as Bwrdd Arthur and Gwal y Filiast stand side by side on the north of and just under a rock outcrop to the east; the two chambers are about 4m apart. The western chamber is the better preserved with a 2.5m long capstone which still rests on surviving orthostats and stands c.1m above ground level. The second chamber to the east has a similar-sized but thicker capstone which rests on the ground along its long north-eastern edge, with two large prone slabs, one to the west and one to the east, as possible side members.

The monument is of national importance for its potential to enhance our knowledge of prehistoric burial and ritual. The monument is an important relic of a prehistoric funerary and ritual landscape and retains significant archaeological potential, with a strong probability of the presence of both intact burial or ritual deposits and environmental and structural evidence, including a buried prehistoric land surface. Chambered tombs 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.
