Neolithic Mounds at Knowth
Knowth near Slane, County Meath, Ireland.
Knowth (Irish: Cnobha) is the site of a Neolithic passage grave, one of the ancient monuments of the Brú na Bóinne complex in the valley of the River Boyne in Ireland.
Knowth is the largest of all passage graves situated within the Brú na Bóinne complex. The site consists of one large mound (known as Site 1) and 17 smaller satellite tombs. Essentially Knowth (Site 1) is a large mound (covering roughly a hectare) and contains two passages, placed along an east-west line. It is encircled by 127 kerbstones (3 of which are missing, 4 are badly damaged). The passages are independent of each other (they do not meet) and both lead to a burial chamber.
