Carreg Bica Round Cairn is a prehistoric round cairn located in Wales and protected by Cadw as a scheduled monument (RD200). The structure was built on bedrock of Llandovery age, comprising mudstone, siltstone and sandstone deposits that underlie the site. These sedimentary rocks, formed during the Llandovery period of the Ordovician era, provided the local substrate upon which the cairn was constructed.
Round cairns of this type typically date to the Bronze Age and served as burial monuments for community members of high status. The cairn would have been built from stone gathered locally, likely including material derived from the weathered Llandovery bedrock exposed in the surrounding landscape. Such monuments often contain cremated remains and associated grave goods, though the specific contents of Carreg Bica are not recorded.
The site preserves evidence of prehistoric funerary practice and settlement patterns in Wales. Its location within the Llandovery Rocks formation reflects how prehistoric communities utilised local geology when siting their monuments. The cairn remains an important record of Bronze Age society in the region and continues to contribute to understanding of contemporary settlement and burial customs across Wales.
