Cairn 270m N of Pont Ffosyrhebog is a prehistoric round cairn located in Wales and protected by Cadw under reference GM313. The monument sits on 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 substantial geological foundation would have provided a stable base for the cairn's construction and contributed stone for the mound itself.
Round cairns of this type were built during the Bronze Age as burial or ceremonial monuments, typically comprising a heaped pile of stones. Their construction in this landscape reflects the sustained use of upland and valley areas by prehistoric communities. The proximity to Pont Ffosyrhebog indicates the cairn's location relative to a significant topographical feature or crossing point, potentially marking a route of importance to its builders.
The monument's survival and official protection demonstrate the archaeological significance of this site within the broader prehistoric heritage of Wales. Such cairns remain valuable sources of information about Bronze Age burial practices, territorial organization and the relationship between early communities and their natural environment.
