Two Ring Cairns West of Cwm Tywyll is a prehistoric ring cairn situated in Wales, protected by Cadw as a scheduled monument under reference ME145. The monument comprises two concentric or adjacent circular stone structures typical of Neolithic or Bronze Age burial practices, when such rings were constructed as ceremonial or funerary focal points in the upland landscape. The cairns are built upon bedrock composed of Caradoc Rocks, a formation of mudstone, siltstone and sandstone laid down during the Caradocian period in the Ordovician. This hard, weathered geology has supported the survival of the stone rings through millennia of exposure to the Welsh climate.
The monument's positioning west of Cwm Tywyll reflects the settlement patterns of prehistoric communities who utilised the uplands for pastoral and ceremonial purposes. The dual cairn structure suggests either a development over time or the simultaneous construction of linked ritual centres, a configuration found at other Bronze Age sites across Britain. Such monuments served as durable territorial markers and focal points for ancestor veneration, persisting in the landscape long after their original construction.
