Knowth

Knowth (Irish: Cnóbha) is a prehistoric tomb overlooking the River Boyne in County Meath, Ireland. It comprises a large passage tomb surrounded by 17 smaller tombs, built during the Neolithic era around 3200 BC. It is the largest passage tomb ever built and contains the largest assemblage of megalithic art in Europe. Knowth is part of the Brú na Bóinne complex, a World Heritage Site that also includes the similar passage tombs of Newgrange and Dowth. After its initial period of use, Knowth gradually became a ruin, although the area continued to be a site of ritual activity in the Bronze Age through to the Iron Age. During the early Middle Ages, a royal residence was built on top of the great mound, which became the seat of the Kings of Knowth or Northern Brega. Archaeologist George Eogan led an extensive investigation of the site from 1962 to 2002, and parts of the monument were reconstructed.
