Cadw's description

The following provides a general description of the Scheduled Ancient Monument.

This large and squat standing stone is situated on the NW shoulder of a hill. It measures 1.3m tall, 1.0m wide, 0.8m deep and 2.8m in circumference. The monument leans slightly to the NW and has a rounded top. Strumble Head and St George's Channel are visible to the N.

The standing stone is thought to be of religious or ceremonial significance and to date to the Bronze Age (c.2300 BC - 800 BC). This example is a local landmark and has important group value as one of a number of surviving standing stones in the immediate vicinity. The monument is likely to retain significant archaeological deposits and enhance our knowledge of prehistoric ritual practices.

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.
