Description

KNOWTH POINT EXTERNAL 3DLINK SMR No.: ME019-030001-

Monument Type: Megalithic tomb - passage tomb

Knowth cemetery, site 1. This great kerbed mound is the focal point of a large passage-tomb cemetery, which has been the site of extensive excavations since 1962. Sixteen small passage-tombs are in close proximity to the main mound and another (ME019-030007-) is 120m to the W. The central mound is c. 90m by 80m by 11m in height. Incurving of the kerb to the E and W indicates entrances to two back-to-back passage-tombs. The W tomb, 34.2m long, comprises a bent passage leading to a simple square chamber; a stone basin lies at bend in passage. The E tomb, 40m long, contains a cruciform chamber with corbelled roof; N recess contains an elaborately decorated stone basin. Many of the kerb stones and large numbers of the structural stones of both tombs are decorated with megalithic art.
