Ballintubber Abbey is an abbey two kilometres northeast of Ballintubber, County Mayo in Ireland that was founded by King Cathal Crobdearg Ua Conchobair in 1216.
History
Despite being suppressed and damaged during the Protestant Reformation, the roofless abbey continued to be used throughout penal times by Catholics. In 1963, extensive archaeological excavations were carried out prior to starting restoration work. By 1966, the nave had been restored and re-roofed, in time for the 750th anniversary of the abbey's foundation although work continued until 1969. In 1997, the Chapter House and Dorter area were restored and re-roofed. In 2016, during the 800th anniversary celebrations, planning permission to restore the entire east wing was granted.
The abbey has several modern outdoor attractions, including a very modern abstract Stations of the Cross, an underground permanent Crib, and a Rosary Way. There is a small museum. According to the Ballintubber website and other popular accounts, John O'Mullowny of Ballyhean, an infamous local priest hunter, is buried in the cemetery. A large tree marks the spot. The abbey marks the beginning of , the ancient pilgrimage route to Croagh Patrick, reopened by Pilgrim Paths of Ireland. A 35-km trail from Ballintubber Abbey to the top of Croagh Patrick has been developed, part of what is also being named the Ireland West Camino, following the model of the Camino de Santiago in Spain.
Architecture
Introduction
Ballintubber Abbey was built in 1216 in the Hiberno Romanesque style, characterized by the chevron archivolts and foliate capitals of the three light-transitional windows to the east. The design is a Latin-cross foundation with a nave, crossing transepts, and a rib-vaulted chancel with two chapels for each side. The abbey has gone through various renovations, mainly on re-building portions that became damaged as it withstood history. There are three renovation attempts to note: the first in 1846 led by Archbishop John MacHale, the second in 1881 overseen by George Coppinger Ashlin, finally, the third restoration in 1909 with Reverend Thomas A. Egan and Percy le Clerc leading the project.
Renovations
In 1265, a fire burned the timber and oak shingles of the nave to ashes, but the stone portion of the east was left standing. The resulting restorations in 1270 had Gothic elements, including the pointed arches seen throughout.
The Cromwellian assault in 1653 destroyed the monastic buildings, dormitories, cloisters, and domestic quarters; all of the timber structures inside the abbey were also taken down. After the assault, only the stone vaulted roofs of the chancel, the four sides of the chapels, and the old sacristy remained.

The first renovation attempts in 1846, led by Archbishop John MacHale, was tasked with re-roofing the nave and the transepts.
The second restoration attempt in 1881-1890 was more successful in completing the project. George Coppinger Ashlin supervised the work being done. With the support of wealthy benefactors, the walls were reinforced, the openings between the transepts were glazed, and the east window of "stained glass of medieval pattern procured from Mayer & Co. of Munich" was installed.
