Hundred House round barrow is a prehistoric round barrow located in Wales and protected by Cadw under reference RD230. The monument sits on bedrock of Wenlock Rocks, an undifferentiated sequence of mudstone, siltstone and sandstone dating to the Wenlock period. These sedimentary deposits, laid down in ancient seas, form the solid geological foundation beneath the barrow's earthwork construction.
Round barrows are Bronze Age burial monuments, typically consisting of a mound of earth and stone raised over cremated or inhumed remains. The Wenlock bedrock underlying Hundred House would have presented particular challenges for Neolithic and Bronze Age communities constructing the barrow, as excavation through such stone requires careful selection of suitable construction materials from the surrounding landscape.
The barrow's survival to the present day, despite millennia of agricultural use and weathering, testifies to the substantial effort invested in its original construction. Its protection by Cadw ensures that this Bronze Age burial monument remains a significant archaeological resource for understanding prehistoric funerary practices and settlement patterns in Wales during the second millennium BC.
