Octagonal lavabo at Old Mellifont Abbey, County Louth

Mellifont Abbey: A Visitor’s Guide to Ireland’s First Cistercian Abbey

Mellifont Abbey, near Drogheda in County Louth, was Ireland’s first Cistercian monastery, founded in 1142. Today its peaceful ruins sit in a quiet river valley a few minutes from Monasterboice, and its rare two-storey octagonal lavabo is one of the finest pieces of medieval monastic building in the country. Here is what to know before you visit.

What is the history of Mellifont Abbey?

Mellifont was founded in 1142 by St Malachy of Armagh, with monks sent by St Bernard from Clairvaux in France. It was the first Cistercian house in Ireland and became the mother house for many others across the country.

Centuries later, Mellifont played a part in a turning point in Irish history. The Treaty of Mellifont was signed here in 1603, ending the Nine Years’ War.

What can you see at Mellifont today?

  • The lavabo. A two-storey octagonal building where the monks washed before meals. Only part of it survives, but its arches make it the highlight of the site.
  • The abbey ruins. Foundations and walls of the church and cloister, laid out in the classic Cistercian plan.
  • The visitor centre. An exhibition on the abbey and the Cistercians, with guided tours in season.
