Newgrange

County Meath

Newgrange is arguably Ireland's most important prehistoric monument and one of the greatest ancient sites in Europe. Built around 3200 BC, this enormous passage tomb is older than both Stonehenge and the Egyptian pyramids.

The monument's most famous feature is its alignment with the winter solstice sunrise. Each year, sunlight enters through a specially designed roof box and illuminates the inner chamber, demonstrating the astronomical knowledge of Ireland's Neolithic builders.

Located within the Boyne Valley, Newgrange is ideal for outdoor travellers, with nearby walking routes, heritage trails and campsites.
