Garreg Round Cairn is a prehistoric cairn located in Wales and protected by Cadw under reference ME107. The monument sits upon bedrock of Middle Cambrian age, comprising mudstone, siltstone and sandstone laid down during the Middle Cambrian period over 500 million years ago. This geological foundation would have been partially exposed across the landscape when the cairn was constructed, providing readily available stone for building.
Round cairns of this type typically date to the Bronze Age and served as burial monuments, though without excavation the precise date and function of Garreg Round Cairn cannot be definitively established. The stones used in its construction would have been gathered from the immediate vicinity, taking advantage of the naturally fractured bedrock characteristic of the Cambrian mudstone and siltstone geology of the region.
Today, Garreg Round Cairn stands as evidence of prehistoric monument-building practices in Wales. Its survival to the present day, coupled with its statutory protection, allows it to contribute to our understanding of Bronze Age burial customs and the relationship between prehistoric communities and their local landscape and geology.
