The monument comprises the remains of a standing stone, which probably dates to the Bronze Age (c. 2300 - 800 BC) and which stands on flat ground on a low hill on the east side of the Gwilli Valley. The standing stone measures c 4m in height, and has a 1 x 0.5m rectangular cross-section.

The monument is of national importance for its potential to enhance our knowledge of prehistoric burial and ritual practices. It is an important relic of a prehistoric funerary and ritual landscape and retains significant archaeological potential. There is a strong probability of the presence of intact burial or ritual deposits, together with environmental and structural evidence. The stone is on record as being one of a wider complex of associated standing stones which are now no longer extent. Standing stones are often 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.
