Cadw's description

The following provides a general description of the Scheduled Monument.

The monument comprises the remains of a large burial cairn, probably dating to the Bronze Age (c.2300 BC - 800 BC) and situated in moorland on the saddle between Little Hill to the S and Llyn-y-waun to the N. The heather-covered cairn is circular on plan and measures about 16.5m in diameter and up to 1.8m in height.

The monument is of national importance for its potential to enhance our knowledge of prehistoric burial and ritual. The well-preserved 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 area scheduled comprises the remains described and an area around them within which related evidence may be expected to survive. It is circular and measures 20m in diameter.
