Cadw's description

The following provides a general description of the Scheduled Monument.

The monument comprises a standing stone, probably dating to the Bronze Age (c.2300 BC - 800 BC). It is a large, flat rounded stone, standing 1.25m in height and measuring 1.5m in thickness and 0.4m in width. The stone is orientated from NNE to SSW, with the larger sides facing ESE and WNW respectively. It is situated in rough grazing on a gentle S-facing slope and is not in a prominent position in the landscape.

The monument is of national importance for its potential to enhance our knowledge of prehistoric ritual practices. The monument retains significant archaeological potential with a strong probability of associated archaeological features and deposits and forms an important element in the wider prehistoric funerary and ritual landscape.

The area scheduled comprises the remains described and an area around them within which related evidence may be expected to survive. It is circular and measures 10m in diameter.
