Knowth is a major Neolithic passage tomb complex located within the Brú na Bóinne World Heritage site. The site features one large central mound surrounded by 17 smaller satellite tombs. It contains the largest collection of Neolithic rock art in Western Europe, accounting for approximately one-third of the total known examples in the region. The central mound houses two separate passages oriented east and west. Excavations conducted since the 1960s have revealed extensive evidence of occupation dating from the Neolithic through the early medieval period. During the 12th century, the site was repurposed as a fortified enclosure by the Anglo-Normans. The site is managed by the Office of Public Works (OPW). Visitors access the site via the Brú na Bóinne Visitor Centre.
