Y Garnedd Wen Round Cairn is a prehistoric round cairn located in Wales and protected by Cadw under reference DE278. The monument sits upon bedrock of Caradoc Rocks, formed during the Caradocian period from mudstone, siltstone and sandstone—a geology typical of the Ordovician deposits that underlie much of mid-Wales. Round cairns of this type generally date to the Bronze Age and served as burial monuments, their stone construction reflecting both practical building methods suited to upland terrain and ritual significance for the communities that erected them. The solid foundation of Caradoc Rocks would have provided a stable base for construction, whilst the surrounding landscape of exposed bedrock would have offered accessible stone for the cairn's building material. The site survives as evidence of early Bronze Age mortuary practice and the settlement patterns of prehistoric Welsh communities.
