Dowth (Irish: Dubhadh) 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, 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.. Archaeological and geophysical field surveys of the entire site, including later monuments, were carried out episodically from 2012-2015. In July 2018, another passage tomb in the grounds of nearby Dowth Hall was excavated, revealing significant examples of Neolithic rock art similar to those at Dowth and the other Brú na Bóinne sites.
