The monastery at Glendalough

The Abbot of Glendalough was the head of the monastery at Glendalough, founded by Saint Kevin in the early sixth century, which is in modern-day County Wicklow, Ireland. After the death of Saint Kevin, the abbots bore the title "Comarbai Cóemgein" (i.e. "successor of Saint Kevin"). Until the early twelfth century, a number of abbots and others at the monastery of Glendalough had also been consecrated bishops, but this did not necessarily mean they were bishops of Glendalough, since the Diocese of Glendalough was not established until the Synod of Rathbreasail in 1111.[1]
