Newgrange (Irish: Sí an Bhrú) is a prehistoric monument located in County Meath, on the eastern side of Ireland, about one kilometre north of the River Boyne.[1] An example of a megalithic passage tomb mound, Newgrange was built between circa 3100 and 2900 BCE, during the Neolithic period, in order to house the remains of the dead. It has also been speculated that it had some form of religious significance, particularly in regards to an afterlife, because it is aligned with the rising sun on the winter solstice, which floods the tomb with light.
The Newgrange monument primarily comprises a large mound, built of alternating layers of earth and stones, with grass growing on top and a reconstructed facade of flattish white quartz stones studded at intervals with large rounded cobbles covering part of the circumference
