Fan Gyhirych is a prehistoric round cairn located in Wales and protected by Cadw under reference BR330. Round cairns of this type, constructed by heaping stone over a central burial, were built throughout the Neolithic and Bronze Age across the British uplands. The monument sits on bedrock of Lower Devonian age, comprising sandstone and conglomerate layers formed during the Early Devonian period. These resistant rocks would have been readily accessible to prehistoric builders in the surrounding landscape.
The cairn's survival in this location reflects both the durability of its stone construction and the relative stability of upland terrain. The underlying geology of interbedded sandstone and conglomerate would have provided naturally available material suitable for cairn building, making this site a practical choice for Bronze Age communities. The monument remains an important archaeological record of prehistoric ritual practice and burial customs in Wales.
