Cadw's description

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

This monument comprises the remains of a round barrow dating to the Bronze Age (c. 2400 - 800 BC). It lies 300m above sea level on flat ground. The circular grass mound measures approx. 12m in diameter and 1.6m high. A central hollow in which stones are visible is located in the top of the barrow and measures approx. 3m in diameter and 1m deep. This is probably the result of past robbing or antiquarian exploration. No ditch is visible around the mound.

The monument is of national importance for its potential to enhance our knowledge of prehistoric burial and ritual. The monument is an important relic of a prehistoric funerary and ritual landscape and retains significant archaeological potential, with a strong probability of the presence of both intact burial or ritual deposits and environmental and structural evidence, including a buried prehistoric land surface.

The scheduled area comprises the remains described and areas around them which related evidence may be expected to survive.
