Gareg Hir Standing Stone is a prehistoric standing stone located in Wales and protected by Cadw under reference CM202. The monument rises from bedrock composed of Ashgill Rocks, undifferentiated strata of mudstone, siltstone and sandstone formed during the Ashgill epoch. This geological foundation, characteristic of the Welsh uplands, provided the stable ground upon which the stone was erected in antiquity.
Standing stones such as Gareg Hir typically date to the Bronze Age or Late Neolithic period, though precise dating for individual monuments is often uncertain without excavation. These monoliths served various purposes in prehistoric communities, from territorial markers to ritual or ceremonial functions, and frequently formed part of broader landscapes of sacred significance.
The stone's survival to the present day, despite millennia of exposure to the Welsh climate and landscape changes, testifies to the durability of the local geology. Today Gareg Hir remains an important record of prehistoric settlement patterns and beliefs in Wales, and its protection by Cadw ensures its preservation for future generations of researchers and visitors.
