This fine standing stone is located on a south facing slope. It measures 1.3m tall, 1.1m wide and 0.8m deep. It is oriented N-S and has a bluntly pointed top. The stone is notable for its very pitted appearance and quartz inclusions.

The standing stone is believed to be of religious or ceremonial significance and to date to the Bronze Age (c.2300 BC - 800 BC). This example possesses important group value as it is the NW component of an alignment of three standing stones. The monument is likely to retain 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.
