Meuryn Isaf Cairn is a prehistoric round cairn situated in Wales and protected by Cadw under reference CN308. The monument stands on bedrock of Llanvirn Rocks, an undifferentiated formation of mudstone, siltstone and sandstone laid down during the Whiterock period. This solid geological foundation would have provided a stable base for construction and would have been well-known to the prehistoric communities who built the monument.
Round cairns of this type typically date to the Bronze Age and served as burial monuments for individuals or small groups. They were constructed by heaping stones over a central burial chamber or cremation deposit, often marking the resting place of a community leader or respected member. The form remained in use across Britain and Ireland for over a thousand years, representing a widespread and persistent tradition of monumental commemoration.
The Llanvirn bedrock underlying Meuryn Isaf would have determined the availability of stone for construction. Local sources of suitable material from the surrounding landscape would have been quarried or gathered to build the cairn. The monument's survival to the present day, despite centuries of weathering and potential disturbance, reflects both the robust construction methods of its builders and the protective status it now enjoys under Cadw's stewardship.
