The Loughinisland Churches are the remains of three ruined churches, dating from the 13th to the 17th centuries. They are situated in Tievenadarragh townland, in a large graveyard on an island in Loughinisland Lake, now reached by a causeway.
The earliest recorded reference is to a parish church on the site in 1306. The Middle Church is the oldest, probably from the 13th century. The large North Church was built in the 15th century, probably to replace the Middle Church, and continued in use until 1720. The smallest is the South (MacCartan's) Church, the elaborately carved west door of which has the date 1636 and initials PMC for Phelim MacCartan. This was probably the main burial ground of the MacCartans who had one of their chief seats near the lake.
The North Church was in use until about 1718. Local accounts say that at one time there was an amicable arrangement for the church to be used for both Protestant and Roman Catholic worship, but that a dispute rose one wet Sunday, when Roman Catholics were unwilling to leave the church due to the rain, and free the church up for the Protestants. This displeased the Forde family so much that they dismantled the old church and built a new one in Seaforde which was roofed with the timbers of the old building.
References:The church of the former Franciscan monastery was built probably between 1515 and 1520. It is located in the UNESCO World Heritage Site of Old Rauma. The church stands by the small stream of Raumanjoki (Rauma river).
The exact age of the Church of the Holy Cross is unknown, but it was built to serve as the monastery church of the Rauma Franciscan Friary. The monastery had been established in the early 15th century and a wooden church was built on this location around the year 1420.
The Church of the Holy Cross served the monastery until 1538, when it was abandoned for a hundred years as the Franciscan friary was disbanded in the Swedish Reformation. The church was re-established as a Lutheran church in 1640, when the nearby Church of the Holy Trinity was destroyed by fire.
The choir of the two-aisle grey granite church features medieval murals and frescoes. The white steeple of the church was built in 1816 and has served as a landmark for seafarers.
