Cadw's description

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

The monument comprises the remains of a earthen built round barrow, which probably date to the Bronze Age (c. 2300 - 800 BC). The barrow is circular in shape on plan, is 23m in diameter and 2m high. The sides of the barrow are steep and the top is flattish, around 6m in diameter, with a slight depression in the centre. The mound was excavated in 1871 by J.E. Thomas who found 5 cists containing cremations, flint tools and a whetstone.

The monument is of national importance for its potential to enhance our knowledge of prehistoric burial and ritual practices. The features are an important relic of a prehistoric funerary and ritual landscape and retain significant archaeological potential. There is a strong probability of the presence of both intact ritual and burial deposits, together with environmental and structural evidence. Barrows may be 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.
