Pen-Lan-Uchaf Standing Stone is a prehistoric standing stone located in Wales and protected by Cadw under reference CM197. The monument rises from bedrock composed of Lower Devonian rocks, a mixture of sandstone and conglomerate laid down during the Early Devonian period. This geological foundation of interbedded sedimentary strata provided the local stone from which such monuments were traditionally raised.
Standing stones of this type date broadly to the Bronze Age and earlier periods, erected as markers, boundary stones, or ritual monuments within the prehistoric landscape. Pen-Lan-Uchaf's position on Early Devonian geology places it within a region of Wales where such stones are found across similar bedrock formations, contributing to the archaeological character of the upland environment.
The monument survives as a testament to prehistoric stone-working practices and the social or ceremonial significance of permanent markers in the Bronze Age and earlier periods. Its preservation under Cadw's protection ensures that this element of Wales's archaeological heritage remains accessible for study and public understanding of the region's deep historical landscape.
