Nant-Gronw Round Barrows

Cadw's description

Summary description and reason for designation

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

The monument comprises the remains of two or possibly three earthen built round barrows, which probably date to the Bronze Age (c. 2300 - 800 BC). The first to the south-west measures 12m in diameter and 1.1m high with boulders showing through the surface. The second, a probable ring cairn located approximately 200m to the east north east comprises a ring bank 2m wide and 0.45m high, the stony interior of which has quantities of white quartz at the surface. The final barrow is recorded as being 12m to the south of the latter and described as a small mound 1m high. However confusion over the identification of another confirmed but unscheduled round barrow 150m to the south means in fact this smaller mound may be the remains of a possible spoil heap dug from the site.

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.
