Overview

History & significance

St Canna's Chair is an early medieval inscribed stone located in Wales and protected by Cadw under reference PE148. The monument sits upon bedrock of Arenig Rocks, a formation of mudstone, siltstone and sandstone dating to the Arenigian period. These hard, ancient stones have provided a stable foundation for the carved stone through more than fourteen centuries.

The stone itself bears inscriptions that date it to the early medieval period, when such carved monuments commonly served commemorative or territorial functions in Wales. The inscription work survives as evidence of skilled stone carving practices during this era, when written markers in stone were typically associated with Christian sites, local leaders or significant individuals within Welsh communities.

The name "Chair" reflects local tradition surrounding the monument, a designation common to several early medieval stones in Wales. The combination of the inscribed surface, its prominent position in the landscape, and its survival through the medieval period onwards makes this a significant record of early medieval Welsh culture and Christian practice in this region.
