Earthwork at Pant-y-Pyllau, Coity Higher is a prehistoric earthwork of unclassified type situated in Wales. The monument lies upon Triassic bedrock composed of interbedded sandstone and conglomerate, geology that has shaped both the landscape and the construction methods available to its builders. This underlying geology is typical of the Triassic period and would have provided suitable stone for any structural works undertaken at the site.
The earthwork's specific form and date remain undetermined, reflecting the challenges of interpreting buried or eroded prehistoric remains without modern excavation. Such unclassified monuments across Wales often represent domestic occupation, ceremonial spaces, or defensive works from periods spanning the Neolithic through to the Bronze Age, though definitive attribution requires archaeological investigation.
The site is protected as a scheduled ancient monument under Cadw, Wales's heritage organisation, and is registered under the reference GM426. This designation recognises the earthwork's archaeological potential and significance to understanding prehistoric settlement and land use patterns in the region, even where its precise character has yet to be established through detailed study.
