Mellifont

Mellifont Abbey (Irish: An Mhainistir Mhór, literally 'the Big Monastery') was a Cistercianabbey located close to Drogheda in County Louth, Ireland. It was the first abbey of the order to be built in Ireland. In 1152, it hosted the Synod of Kells-Mellifont. After its dissolution in 1539, the abbey became a private manor house. This saw the signing of the Treaty of Mellifont in 1603 and served as William of Orange's headquarters in 1690 during the Battle of the Boyne.
