Foel Drygarn

Foel Drygarn, the hill of the three cairns, is an Iron Age hillfort in Pembrokeshire, Wales. The site, about 1.5 miles west of Crymych, likely served as an important center. An inner defense on the summit encloses 1.2 hectares. Sabine Baring-Gould, who excavated the site in 1899, discovered both Iron Age and Roman relics, including glass beads and sling stones.

The hill, the furthest east of the Preseli Hills, can be seen from miles around, and the fort was probably an important center in its time. Each defense, built at later stages on the north and east side, is a single rampart of dry stone and earth, with traces of a ditch outside the inner rampart.

Within the inner defense are three stone cairns, regarded as Bronze Age burial mounds. The site also has at least 227 hut platforms. 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. The builders evidently respected their Bronze Age predecessors, as the cairns were not plundered for the stone.
