The Abbey was founded in 1204 by William Marshall the elder, earl of Pembroke, and was colonised with monks from Stanley in Wiltshire. The monks may not have arrived at Graiguenamangh until 1207, but it seems that building may have begun in 1204 when the cemetery at Duiske was consecrated. In 1228 the religious community was fixed at thirty-six monks and fifty lay-brothers which was almost as large as Mellifont Abbey. The abbot of Duiske sat as a peer in parliament at that time. The Abbey was suppressed under Henry VIII in 1536 and the last abbot, Charles O'Cavanagh, resigned his title. Monks continued to occupy it but it began to fall into ruin. Following the dissolution the lands were awarded to James Butler of Duiske. The abbey church continued to be used as a local place of worship. The Church of Ireland re-roofed the west end after the tower collapsed into the nave in 1744. The church was returned to the Roman Catholic community in 1812 and restoration was completed in the 1980s. Currently it is used as a parish church and music events are held there.
Building
Duiske Abbey was one of the first, largest and perhaps the finest of the thirty-four medieval Cistercian monasteries in Ireland. Much of the abbey was constructed with yellow limestone brought across the Irish Sea from quarries at Dundry, outside Bristol. Significant remains of the monastery still exist and the remains are fully restored as an early Cistercian Church. Original medieval floor tiles from the original building can be seen in the abbey along with the beautiful "Early English" gothic and romanesque architecture. Some of the 13th-century stonework can still be seen, including still-leaf foliage carved into the capitals, dog-tooth ornaments and banded shafts. It contains many Lancet windows. An effigy of a 13th-century Norman Knight found in the ruins is installed by the main entrance. He is depicted seizing a sword and is carved with great attention to detail. It is one of the finest medieval effigies in Ireland. In its northern aisle a model of the monastery shows the abbey as it was in the 14th century. Explanation plaques are at various points in the Abbey. In the nearby Abbey Centre there is an exhibition of contemporary Christian Art and local historic artefacts.
