What is "dowth"

Dowth is a Neolithic passage tomb located in the Boyne Valley, County Meath, Ireland that dates from about 2,5002000 BC. It is the second oldest behind Newgrange of the three principal tombs of the Brú na Bóinne World Heritage Sitea landscape of prehistoric monuments including the large passage-tombs of Dowth, Newgrange and Knowth). It is less developed as a tourist attraction than its neighbours, partly because the chamber is much lower, and partly because the decoration is poorer. It was partly excavated in 1847, though it was pillaged by Vikings and earlier looters long before that.
