Standing Stone on Mynydd Illtud is a prehistoric standing stone situated on open moorland in Wales, protected as a Scheduled Ancient Monument under Cadw reference BR228. The monument consists of a single upright stone typical of Bronze Age or later prehistoric ritual and territorial practice in upland regions. Such stones often marked boundaries, burial sites, meeting places or astronomical alignments significant to the communities who erected them.
The stone stands upon bedrock of Lower Devonian rocks, laid down during the Early Devonian period some 410 to 395 million years ago. The underlying geology comprises undifferentiated mudstone, siltstone and sandstone, characteristic of the sedimentary deposits formed in shallow marine and river environments of that distant era. The weathered state of these ancient strata would have been familiar to later prehistoric peoples who knew this landscape intimately.
The moorland setting of Mynydd Illtud, exposed and commanding views across surrounding terrain, is typical of locations chosen for standing stones in upland Wales. Such positions offered visibility from considerable distances and were often selected for their natural prominence. The stone's survival and protection reflect its significance as a physical record of prehistoric use of this upland zone, preserved within the modern landscape as evidence of ancient settlement and ritual practice.
