The so-called abbey in Mungret, County Limerick. There had been a monastery here, supposedly founded in the mid-sixth century by Saint Nessan, but due to frequent assault and despoliation over subsequent centuries, no trace of the original buildings survives. Instead, what can be found here dates back to the 12th and 13th centuries. In 1179 Donal Mór O Brien, King of Leinster granted the monastery and its lands to the Bishop of Limerick, and this subsequently became a parish church for Augustinian Canons Regular. The building is divided into three sections, the oldest part at the east end being the chancel, followed by the nave and then, at the west end, a square tower added in the 15th century and incorporating living quarters for a priest. Following the 16th century Reformation, the building continued to be used by the Church of Ireland until replaced by a new church designed by the Pain brothers in 1822 and located a short distance to the west of the older structure. The Pains’ work – which took the form of a Greek cross – did not survive long, since falling numbers of parishioners meant the new church at Mungret closed just 55 years later in 1877, before being unroofed in 1900, with much of the stone then reused to build a parochial house in nearby Raheen.
