# Bishop of Glendalough

The Bishop of Glendalough (Irish: Easpuig Gleann Dá Loch) is an episcopal title in the Church of Ireland, which takes its name after the monastery at Glendalough in County Wicklow, Ireland. An Irish version of the place name, Glenndálocha, is now used for a titular see in the Roman Catholic Church.

## History

The diocese of Glendalough was one of the dioceses established at the Synod of Rathbreasail, held in 1111. After the death of Bishop William Piro and the failed effort to get possession of the see by Bishop-elect Robert de Bedford, the dioceses of Glendalough and Dublin were united in 1214. The union of the two was confirmed by Pope Innocent III on 25 February 1216, and confirmed again by Pope Honorius III on 6 October 1216. During the late fifteenth and early sixteenth centuries, a number of titular bishops were appointed, but none of them had effective possession of the see. After the Reformation in Ireland, the title Bishop of Glendalough was dropped by the Roman Catholic archbishops of Dublin, but is still used by the Church of Ireland archbishops of Dublin.
In 1969, an Irish version of the place name, Glenndálocha, is now used by Roman Catholic Church for a titular see which is currently vacant.
