Cadw's description

The following provides a general description of the Scheduled Monument.

The monument comprises a massive standing stone, probably dating to the Bronze Age (c.2300 BC - 800 BC) and situated within enclosed pasture about 200m to the NE of Werthyr Farm. The standing stone measures about 3m in height, 1.8m in thickness from NE to SW by 0.8m in width. Several packing stones are visible around its base.

The monument is of national importance for its potential to enhance our knowledge of prehistoric ritual practices. The monument is well preserved and is an important relic of a prehistoric funerary and ritual landscape. It retains significant archaeological potential, with a strong probability of the presence of associated archaeological features and deposits.

The area to be scheduled comprises the remains described and an area around them within which related evidence may be expected to survive. It is circular and measures 6m in diameter.
