Knowth is one of three prehistoric burial mounds in Ireland which make up the World Heritage site of the Bend of the Boyne (Brugh na Boinne).
The oldest aspects of Knowth date back to the Neolithic period, moving through to the Iron Age when it was fortified. Knowth thrived as a settlement from the 8th century AD and, whilst located not far from three large ring forts built at the time, was itself undefended. Falling to the Normans in the 12th century, Knowth developed to play an agricultural role.
Visitors to the Bend of the Boyne can see Knowth together with the other two mounds, Newgrange and Dowth. Knowth itself includes tens of ruins ranging from small passage graves to occupation sites to its large passage tomb.
A visit to the visitor centre plus Knowth take about 2 hours or, for those who also want to see Newgrange, about 3 hours.
