Cadw's description

The following provides a general description of the Scheduled Monument.

The monument comprises the remains of two standing stones, which probably date to the Bronze Age (c. 2300 - 800 BC).

The stones are situated 3.25 m apart. The taller stone is about 4 m high, 3 m wide and 0.4 m thick. The other, situated to the east-north-east of the first, is about 3 m high, 2.4 m wide and 1.5 m thick. The west stone was formerly used as a gatepost on a field bank running southwest-northeast, and the east stone lies a short distance south-east of the bank.

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.
