The monument comprises the remains of a large, impressive and well-preserved standing stone, which probably date to the Early Bronze Age (c. 2000-1500 BC). It is some 3.0m high, 0.90m wide and 0.75m thick, with the longer axis aligned east to west. It is currently embodied in the wall of a drystone sheepfold. The monument is associated with the Fonllech Hir prehistoric trackway.

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 be 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.
