Penrhosfeilw Standing Stones is a prehistoric standing stone located in Wales, protected by Cadw under reference AN017. The monument stands upon bedrock of Upper Cambrian metasedimentary rock, including Tremadoc formation material laid down during the Tremadocian period. This ancient geological foundation, some 485 million years old, provides the underlying slate and mudstone that characterises the local landscape.
Standing stones of this type typically date to the Neolithic or Bronze Age periods, erected as territorial markers, burial monuments, or ritual focal points within prehistoric communities. The Tremadoc geology of the region would have been familiar to these early peoples, who selected stone from the local bedrock for construction and daily use.
