Llethrau Camp is a prehistoric enclosure situated in Wales and protected by Cadw as a monument of national importance under reference RD107. The site overlies Pridoli bedrock, geological strata comprising mudstone, siltstone and sandstone laid down during the Pridoli epoch, which provides the underlying foundation for the earthwork.
The enclosure represents a form of settlement or defensive structure characteristic of prehistoric Wales, with its ramparts and ditches cut into and constructed upon the solid Pridoli geology. Such camps served diverse purposes across different periods: some functioned as seasonal gathering places or cattle pounds, whilst others formed more permanent defended settlements. The specific form and arrangement of Llethrau Camp's earthworks reflect the landscape management practices and building traditions of its era.
The monument's survival depends upon the stability of its underlying mudstone and siltstone bedrock, which has protected the archaeological deposits from significant disturbance. Cadw's protection ensures that future investigation may recover further evidence of the site's function, chronology and the communities who constructed and inhabited this camp during prehistory.
