Entrance to Newgrange
Newgrange is a prehistoric monument located in County Meath, Ireland. It was built around 3200 BC during the Neolithic period. There is no agreement about what the site was used for, but it has been speculated that it had some form of religious significance because it is aligned with the rising sun, which floods the stone room with light on the winter solstice. Newgrange is also older than Stonehenge and the great pyramids of Giza.
The Tuatha Dé Danann, who ruled Ireland in ancient mythology, were said to have erected Newgrange as a burial place for their chief, Dagda Mór, and his three sons. One of his sons, called Aonghus, is often referred to as Aonghus of the Brugh, and it was traditionally believed that he, in fact, was owner of the Brugh, and that a smaller mound between Newgrange and the Boyne was owned by the Dagda.
