Llansadurnen Cross-Incised Stone & Other Stones is an early medieval monument comprising a cross-marked stone and associated stones located in Wales. The principal stone bears incised cross markings characteristic of early medieval ecclesiastical sites, likely dating to the Early Christian period when such marked stones served ritual, commemorative or territorial functions within monastic or Christian communities. The monument's exact original purpose remains open to interpretation, though cross-marked stones of this type are commonly found in association with early church settlements or burial grounds across Wales and the wider Celtic regions.
The site sits upon Pridoli rocks, a geological formation of mudstone, siltstone and sandstone deposited during the Pridoli epoch. This mixed sedimentary geology would have provided the material for the inscribed stone itself, making the monument deeply rooted in its local landscape. The weathered surface of the incised cross testifies to centuries of exposure to the Welsh climate.
The monument is protected by Cadw, the historic monuments service of Wales, under reference CM136. This designation ensures the preservation of the cross-incised stone and its associated stones for future study and public access, recognising their significance as material witnesses to early medieval Christian culture in Wales.
