Bwlch y Ddeufaen Standing Stones is a prehistoric monument comprising two standing stones located in Wales. The site is protected by Cadw, the Welsh heritage body, under reference CN129. These stones represent an enduring example of monumental stone-setting practice that flourished during the prehistoric period in Britain and Wales.
The stones rise from bedrock composed of Ordovician extrusive rocks, specifically felsic tuff formed during the Ordovician period over 440 million years ago. This geological foundation would have been exposed during the prehistoric period when the stones were erected, providing a notable natural feature in the landscape. The choice of location may reflect the visual prominence of the outcropping rock.
Standing stone monuments such as these served significant social and ritual purposes in prehistoric Welsh communities. Whether erected as territorial markers, ceremonial focal points, or memorials, these stones demonstrate the considerable effort invested by their creators in establishing permanent monuments within the landscape. The survival of two stones at this location provides valuable evidence of prehistoric settlement patterns and cultural practices in Wales.
