The site is about 1.5 miles (2 km) west of the village of Crymych in Pembrokeshire, Wales.

[1][2] Within the inner defence are three stone cairns, regarded as Bronze Age burial mounds.

The remains represent a long period of occupation of the fort, and it is supposed that not all the dwellings were in use at the same time.

Their builders evidently respected their Bronze Age predecessors, as the cairns were not plundered for the stone.

[1][2] Sabine Baring-Gould, excavating the site in 1899, found Iron Age and Roman pottery, glass beads and many sling stones.
