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 southern stone measures 1.85 m high by 0.75 m square. The stone fell over in 1977, and was re-erected following excavation, which revealed that the stone hole had been preceded by an earlier small pit which, it is suggested, could have held a wooden post or earlier stone. The northern stone stands 2.8 m high and is 0.8 m wide by 0.5 m thick.

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.
