Nant y Gledrydd Standing Stone is a prehistoric standing stone located in Wales and protected as a scheduled monument by Cadw under reference CN395. The stone stands upon bedrock composed of Ordovician extrusive rocks, felsic lavas that crystallised over 440 million years ago when volcanic activity dominated this part of ancient Britain. These hard, silica-rich volcanic deposits provided the local geology from which standing stones of this era were often selected and quarried.
Standing stones of this type are characteristic monuments of the Bronze Age, though some may have earlier Neolithic origins. Such stones typically served ritual, ceremonial or territorial functions within prehistoric communities, marking significant locations in the landscape. Their longevity has allowed them to survive millennia of landscape change and land use.
The monument's survival within the Welsh uplands reflects both the durability of its stone and the relative continuity of the open moorland setting in which it stands. Recording and protection under Cadw's scheduling system ensures the site remains preserved for archaeological study and public access, contributing to understanding of prehistoric settlement and ritual practices across Wales.
