Holycross (Irish: Mainistir na Croiche)[2] is a village and civil parish in County Tipperary, Ireland.

The village developed around the Cistercian Holy Cross Abbey on the River Suir.

Holy Cross Abbey was founded in 1180 by King Domnall Mór Ua Briain and was renovated and added to during the 15th century.

The late Dr. Thomas Morris, Archbishop of Cashel and Emly, inspired the reconstruction of the Abbey which was opened in 1975.

[citation needed] In 1975, on the restoration and reconsecration of the Abbey, an artifact, purportedly a relic of the true cross, was reinstated after several centuries.
