Clos-Teg Standing Stones is a prehistoric standing stone monument situated in Wales and protected by Cadw under reference CM123. The stone rises from bedrock composed of Pridoli rocks—undifferentiated mudstone, siltstone and sandstone deposited during the Pridoli epoch. These fine-grained sedimentary foundations would have presented a challenging landscape for Neolithic or Bronze Age communities raising such monuments, requiring considerable effort to excavate and secure the standing stone against the resistant bedrock geology of the region.
Standing stones of this type typically date to the Bronze Age, though some may originate from the later Neolithic period. Their exact ceremonial, territorial or commemorative purpose remains uncertain, though they often mark significant landscape features or formed part of wider ritual complexes. The survival of Clos-Teg demonstrates the enduring presence of these monumental markers across the Welsh uplands and lowlands, serving as tangible evidence of prehistoric settlement and belief systems.
The monument's designation as a protected heritage site recognises its archaeological significance and rarity value. Such standing stones represent irreplaceable records of prehistoric societies and their relationship with the landscape, preserving information about past communities' technological capabilities, social organisation and spiritual practices that cannot be recovered through other means.
