Carreg Bica Standing Stone is a prehistoric monolith located in Wales and protected as a scheduled monument by Cadw under reference GM382. The stone stands upon bedrock of the South Wales Upper Coal Measures Formation, a geological sequence laid down during the Westphalian period and composed of mudstone, siltstone, sandstone, coal, ironstone and ferricrete. This solid foundation of industrial-era geology provides the landscape into which the monument's creators set their stone many thousands of years earlier.
Standing stones of this type typically date to the Bronze Age or earlier Neolithic period, when communities marked their territories, marked burial sites, or served ceremonial and ritual purposes across the British landscape. The specific quartzite or sandstone used in such monuments was often selected for its durability and visual prominence in the local terrain.
Carreg Bica's position upon the Coal Measures bedrock places it within south Wales's distinctive geological zone, an area rich in mineral resources that would later drive industrial development. The monument preserves evidence of prehistoric use of this landscape, standing as a physical record of human activity long before the coal beneath the surface became valued by modern society.
