Duleek, County Meath derives its name from the Irish words daimh liag meaning house of stone and is, it seems, the oldest known reference to such a church being made from stone rather than wood. A monastery was founded here in the fifth century by St Cianán, a disciple of St Patrick, but the ruins of St Mary’s Augustinian priory seen here date from the 12th and 13th centuries, with the large tower at the west end erected in the 15th century at a time when churches and monasteries were subject to attack. An adjacent early 19th century Anglican church no longer serves its intended purpose but has been converted into a restaurant.
