Crugyn Bank Dyke is an early medieval linear earthwork in Wales, built across terrain underlain by Ludlow Rocks, a sequence of mudstones, siltstones and sandstones formed during the Ludlow period of the Silurian era. The monument is protected as a scheduled ancient monument by Cadw under reference MG062.
Linear earthworks of this type were typically constructed between the 5th and 11th centuries across Britain and Wales, serving variously as territorial boundaries, defensive barriers or stock enclosures. The dyke's alignment and construction took advantage of the local geology, which would have shaped how the earthwork was built and how effectively it functioned across the landscape.
The monument remains a significant archaeological record of early medieval land management and social organisation. Its preservation under Cadw's protection ensures that this earthwork, cut into and built upon the Silurian bedrock of Wales, continues to provide evidence of the period's territorial divisions and the practical use of the natural landscape by its inhabitants.
