Old Mellifont Cistercian Abbey Monastic Site

Mellifont Abbey was the first Cistercian monastery in Ireland. St Malachy of Armagh created it in 1142 with the help of a small number of monks sent by St Bernard from Clairvaux. The monks did not take well to Ireland and soon returned to France, but the abbey was completed anyway and duly consecrated with great pomp.

It has several extraordinary architectural features, the foremost of which is the two-storey octagonal lavabo.

The monks at Mellifont hosted a critical synod in 1152. The abbey was central to the history of later centuries, too, even though it was in private hands by then. The Treaty of Mellifont, which ended the Nine Years War, was signed here in 1603, and William of Orange used the abbey as his headquarters during the momentous Battle of the Boyne.
