The monument consists of two standing stones probably dating to the Bronze Age. They stand 3.25 m apart and located in a saddle between two small hills. The south west stone is c. 2.8 m high, 1 m wide at the base and 0.2 m thick. The other stone is 3 m high, 1 m wide at the base and 0.2 m thick. They are aligned on a north-north-east by south-south-west axis. There is a tradition that there was a stone cist found between the stones, containing bones, spear heads and arrow heads.

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.
