Newgrange is a prehistoric monument in County Meath, Ireland, located eight kilometers west of Drogheda on the north side of the River Boyne. It was built during the Neolithic period, around 3200 BC, making it older than Stonehenge and the Egyptian pyramids. The site consists of a large circular mound with an inner stone passageway and chambers. Human bones and possible grave goods or votive offerings were found in these chambers.
