Garn Las ring cairn is a prehistoric ring cairn located in Wales. The monument stands upon bedrock of Lower Devonian age, comprising interbedded sandstone and conglomerate formed during the Early Devonian period. This geological foundation provided the raw material from which the cairn's stones were derived, making use of locally available stone typical of the region.
Ring cairns are a distinctive form of prehistoric monument, consisting of a circular bank of stones with an open or lightly filled interior, thought to date primarily to the Bronze Age. They often served ceremonial or funerary purposes, though their precise function remains debated among archaeologists. Garn Las represents this monument type within its Welsh landscape setting.
The cairn is protected and scheduled as an ancient monument under Cadw, the historic monuments service of Wales, under reference number BR338. This official designation reflects its archaeological and historical significance as a record of prehistoric activity and burial practice in the region.
