Circular Platforms North West of Hen Ddinbych is a prehistoric platform cairn located in Wales and protected as a scheduled ancient monument by Cadw under reference DE087. The site sits upon bedrock of Wenlock Rocks, an undifferentiated sequence of mudstone, siltstone and sandstone deposited during the Wenlock epoch of the Silurian period. This geology provided the stone readily available to the monument's builders in prehistoric times.
Platform cairns are typically interpreted as ceremonial or ritual structures, though their precise function remains uncertain. The circular form of this example suggests construction during the Neolithic or Early Bronze Age, when such monuments were erected across Wales and the broader British landscape. The monument's position on the local bedrock geology would have made construction feasible with materials close at hand.
The site survives today as evidence of prehistoric activity in this region, preserved within the scheduled monument framework to protect it from damage and development. Its location north-west of Hen Ddinbych and its setting on Wenlock bedrock contribute to understanding the prehistoric use of the Welsh uplands and the relationship between monument construction and local landscape geology.
