Carnedd gron ganol, Pen Plynlimon-Fawr

Carnedd gron ganol stands on the summit ridge of Pen Plynlimon-Fawr in Ceredigion. It is a round cairn built late in the Stone Age and early in the Bronze Age. The site sits within the Blaenrheidol community, marked on maps at grid reference SN789869. Its purpose was probably part of burial rituals and ceremonies for the dead. Round cairns differ from ring cairns, which have a surrounding circle of stones. Cadw has listed the cairn as an ancient monument under the number CD037. Local people who raised the cairn also built chambered tombs, burial mounds, stone circles, hillforts, Irish huts and standing stones. These structures show how widely Neolithic and Bronze Age communities spread across the Welsh uplands. Visitors reach the cairn by following the summit ridge of Pen Plynlimon-Fawr. The view stretches across rolling moorland and distant hills. The cairn itself is a low, grass-covered mound of stones. It stands as a reminder of the people who lived and buried their dead here thousands of years ago.
