The monument comprises the remains of a burial chamber dating to the Neolithic (c. 4400-2900 BC). A low roughly rectangular mound stretches out approximately 30m to the west of the chamber. The burial chamber has an entrance on the east side and is constructed from three large mudstone uprights and a capstone. It is unusually high and may never have been completely covered by the surrounding mound.

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.

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