Standing Stone 300m WNW of Cilmoor is a prehistoric standing stone located in Wales and protected as a scheduled ancient monument by Cadw under reference PE521. The stone rises from bedrock formed of Arenig Rocks, undifferentiated deposits of mudstone, siltstone and sandstone laid down during the Arenigian period of the Ordovician. This geology, typical of upland Wales, provided both the raw material for the monument and the challenging terrain in which it was erected.
Standing stones of this type were raised across Britain and Ireland during the Neolithic and Bronze Age periods, though many lack precise dating. They frequently marked territorial boundaries, served as waymarkers across open moorland, or held ritual significance within prehistoric communities. Their continued prominence in the landscape often explains their survival into modern times, whereas smaller contemporary monuments have frequently disappeared.
The stone's position 300 metres west-northwest of Cilmoor places it within the scattered pattern of prehistoric monuments characteristic of Welsh uplands. Its survival and protection reflect the importance placed on preserving these monuments as evidence of early human activity and land use. The undifferentiated geology of its setting demonstrates the enduring relationship between these early communities and the natural landscape they inhabited.
