Cerrig Arthur Stone Circle is a prehistoric stone circle situated in Wales and protected by Cadw under reference ME114. The monument stands upon bedrock of Middle Cambrian age, comprising mudstone, siltstone and sandstone that were deposited during the Middle Cambrian period around 500 million years ago. This ancient geological foundation has provided a stable platform for the circle's stones through millennia of exposure to the Welsh landscape.
Stone circles of this type were constructed during the Bronze Age, typically between 3000 and 1000 BC, and served purposes that likely encompassed ritual, ceremonial and astronomical observation. The specific arrangement of stones at Cerrig Arthur would have required considerable labour and planning, reflecting the significance placed upon such monuments by prehistoric communities. The local bedrock geology would have influenced both the availability of suitable stone and the construction methods employed.
The monument remains an important record of prehistoric religious and social practice in Wales. Its survival to the present day, protected under Cadw's guardianship, enables continued study of Bronze Age ceremonial landscapes and the relationship between ancient peoples and their surrounding environment. The site contributes to understanding the distribution and character of stone circles across the Welsh uplands.
