Llynnau Cregennen Standing Stone is a prehistoric standing stone located in Wales and protected by Cadw under reference ME068. The monument rises from bedrock formed during the Silurian period, an unnamed igneous intrusion of felsic rock composition that emerged in the complex geological landscape of Ordovician to Silurian times. This ancient geological foundation provides the stone matrix from which the monument was ultimately hewn and erected.
The stone stands within a region shaped by substantial tectonic activity during the early Palaeozoic era. The felsic igneous bedrock—likely granitic or similar light-coloured crystalline material—would have been visible and accessible to prehistoric communities familiar with the surrounding uplands. Such deposits were valued sources of durable stone for monumental purposes across Bronze Age and earlier societies in Wales.
The monument's survival into the modern period reflects both the enduring quality of its geological setting and generations of local custodianship. Its formal protection by Cadw recognises its significance as part of Wales's prehistoric heritage. The stone's isolation on the landscape, characteristic of many such monuments, continues to mark a location of considerable antiquity and ceremonial importance within the Welsh uplands.
