Nant Cletwr barrow is a prehistoric round barrow located in Wales and protected by Cadw as a scheduled monument under reference RD215. Round barrows of this type were constructed during the Bronze Age as burial mounds, typically serving as communal or elite sepulchral monuments. The barrow sits upon bedrock composed of Llandovery Rocks, an undifferentiated sandstone and conglomerate sequence formed during the Llandovery period of the Ordovician era, which provides the underlying geological foundation for the monument.
The construction of the barrow would have utilised materials available in its immediate landscape, working upon the stable sandstone and conglomerate base. The geology of the surrounding area, characterised by these interbedded sedimentary rocks, would have influenced the burial practices and settlement patterns of Bronze Age communities in this region of Wales.
As a scheduled monument under Cadw's protection, Nant Cletwr barrow represents an important surviving example of prehistoric funerary architecture. Such monuments provide archaeological evidence of Bronze Age burial customs, social organisation and land use in Wales, contributing to our understanding of prehistoric Welsh societies.
