The neolithic passage tomb complex in Ireland, older than the Egyptian pyramids, is Brú na Bóinne.
Located in County Meath along a bend of the River Boyne, Brú na Bóinne is a vast ritual landscape containing roughly 90 prehistoric monuments. Its best-known passage tombs are Newgrange, Knowth and Dowth, built mainly between about 3300 and 2900 BC—centuries before Egypt’s pyramids.
Newgrange is especially famous for its winter-solstice alignment: sunlight enters through a roof box above the entrance and reaches the inner chamber at dawn. Knowth contains an exceptional concentration of megalithic art, while Dowth has its own astronomical associations. The complex also includes standing stones, burial mounds, enclosures and later ceremonial remains.
A common mix-up is treating Newgrange as the name of the entire World Heritage property. Newgrange is the most famous monument within Brú na Bóinne, whose official UNESCO title is “Brú na Bóinne – Archaeological Ensemble of the Bend of the Boyne.” UNESCO inscribed it in 1993.
