The monument comprises the remains of a standing stone, which probably dates to the Bronze Age (c. 2300 - 800 BC). Pegwn Mawr is located on a gentle E-facing slope overlooking a steep sided gully to the N. The standing stone measures 0.64m in height, 0.55m in length (N-S) and 0.38m in width (E-W). It is sub-rectangular in shape on plan at its base, rising to a blunt and rounded tip. The stone is earthfast with packing stones visible on the N and S sides.

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. 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.
