clipped from www.megalithicireland.com Although not the oldest passage tomb in Ireland, Newgrange is without doubt Irelands best known prehistoric monument. Dated to around 3200 BC, Newgrange is 1,000 older than Stonehenge and centuries older than the great pyramids of Egypt. The earliest passage tombs in Ireland are on the West coast in County Sligo and there construction and design developed as they spread across to the East coast culminating in the great complex at the Boyne Valley.
