The Cistercian foundation declined and was replaced with a Dominican friary dedicated to Saint Mary Assumed into Heaven, Peter and Paul, founded in 1426 by Murchad Ó Madáin of the powerful O'Madden lords of Síol Anmchadha.
The friary was reestablished in 1640, with Ambrose Ó Madadhan the first prior. Richard Ó Madadhan was prior in 1691, when the friars were forced to flee after the Battle of Aughrim. Anthony McHugo was the prior when the Dominicans were formally expelled on 1 May 1698. Some remained and by the early 18th century they had reoccupied the priory. McHugo died there on 24 July 1711. The friars continued to live in the area, at Boula and at Gortanumera up to the 19th century.
