Graig Lwyd: A Neolithic Axe Landscape in North Wales [10:19]

In the hills of north Wales there is a great deal of archaeology. From standing stones, circles, cists and cairns, there is plenty to see today. However there is a type of stone used in the Neolithic that was clearly very important for its ability to be flaked. Its not flint, instead its a volcanic rock that could be flaked in the same way and ground into axe heads. These axe heads have been found hundreds of miles away from north Wales which demonstrates their high value.
