The monument consists of the remains of a long barrow dated to the Neolithic (c. 4400 - 2400 BC) and an earthen round barrow of probable Bronze Age date (c. 2300-800 BC). The long barrow is ill-defined in plan, measuring around 16m in length by 10m wide and 1.5m high. Excavation revealed that the monument contains one large and two small megalithic chambers containing articulated and disarticulated human bones, pottery and flint. The round barrow is circular in plan, around 15m in diameter and 1.5m high. Excavation revealed that it was enclosed by a stone kerb. Both monuments are located within a modern housing estate.
The monument is of national importance for its potential to enhance our knowledge of prehistoric burial and ritual. The barrows are an important relic of a prehistoric funerary and ritual landscape and retain 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. 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.
