Dowth is a Neolithic passage tomb located in the Boyne Valley, County Meath, Ireland. It is one of the three principal tombs of the Brú na Bóinne World Heritage Site – a landscape of prehistoric monuments including the large passage-tombs of Dowth, Dowth Hall, Newgrange and Knowth. Unlike Newgrange and Knowth, Dowth has not been independently dated, but its features align it with the other passage tombs which date from between approximately 3200 and 2900 BC. However, Harbison (1970) dates the tomb at 2500 – 2000 BC. It is less developed as a tourist attraction than its neighbours, partly because the chamber is much lower, and partly because the decoration is less visible. It was partly excavated, in 1847 by the Royal Irish Academy who dynamited the roof causing the still visible crater, though it was pillaged by Vikings and earlier looters long before that.

Knowth is a Neolithic passage grave and an ancient monument of the World Heritage Site of Brú na Bóinne located 8.4 km west of Drogheda in Ireland's valley of the River Boyne. It is the largest passage grave of the Brú na Bóinne complex. It consists of a large mound and 17 smaller satellite tombs. The mound is about 12 metres (40 ft) high and 67 metres (220 ft) in diameter, covering roughly a hectare. It contains two passages placed along an east-west line and is encircled by 127 kerbstones, of which three are missing, and four badly damaged.

Newgrange is a prehistoric monument in County Meath in Ireland, located on a rise overlooking the River Boyne, 8 kilometres (5.0 mi) west of Drogheda. It is an exceptionally grand passage tomb built during the Neolithic Period, around 3200 BC, making it older than Stonehenge and the Egyptian pyramids. It is aligned on the winter solstice sunrise. Newgrange is the main monument in the Brú na Bóinne complex, a World Heritage Site that also includes the passage tombs of Knowth and Dowth, as well as other henges, burial mounds and standing stones.
