The monument consists of the remains of a chambered tomb, dating to the Neolithic period. Chambered tombs were built and used by local farming communities over long periods of time. This megalithic chamber is comprised of a massive capstone nearly 1 m thick at the east end resting on three uprights, each about 1 m high. A fourth upright is free-standing. The capstone, over 3.5 m long, has split and extra support has been provided in the form of two stone pillars. The site was excavated in 1936, but little of significance was discovered except the tracing of the original chamber by a charcoal spread, which showed that the capstone did not cover its complete extent. The field in which the monument stands has been regularly ploughed, leaving the chamber standing on a slightly raised platform. A bed of concrete, laid after the 1936 excavations, covers much of this raised platform. Early references to the site may indicate the previous existence of a second chamber close by.

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 an area around them within which related evidence may be expected to survive.
