A nice example of Pembrokeshire Blue Stone which appears to have been worked into shape by ancient man. The stone stands in a wild flower meadow at Cilgwyn Mill, Newcastle Emlyn. A team of three geologists including Dr Richard Bevins, Keeper of Natural Sciences at the National Museum of Wales in Cardiff, have identified a hill called Carn Goedog, about three miles from Crymrch in the Preseli Hills of Pembrokeshire, as the site from which 11 stones known as spotted dolerites were somehow transported to Stonehenge in Wiltshire.
