he following provides a general description of the Scheduled Monument. The monument comprises the remains of a burial cairn and an associated standing stone, both probably dating to the Bronze Age (c.2300 BC - 800 BC) and situated on the S-facing leading edge of a local summit on the SW-facing slopes of Mynydd Trawsnant. The grass-covered cairn, which probably utilises an outcropping bedrock knoll, is circular on plan and measures about 16m in diameter and up to 1.6m in height. An impressive quartz standing stone is situated about 45m to the NNW. It is a large block of stone, measuring 0.9m in height by 0.6m in width and 0.6m in thickness. Packing stones are clearly visible around its base. The monument is of national importance for its potential to enhance our knowledge of prehistoric burial and ritual practices. 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. The importance of the monument is further enhanced by the group value formed by the association of the burial cairn and quartz standing stone. The area scheduled comprises the remains described and areas around them within which related evidence may be expected to survive. Area A (SN 7933 4304) is circular and measures 28m in diameter. Area B (SN 7933 4309) is circular and measures 12m in diameter.
