cathedral

Dedicated to Saint Peter and Saint Paul, the Cathedral is the largest surviving ruin and it occupies the most prominent position in Glendalough. Originally dating to the time of Kevin himself, it underwent many alterations over the centuries and now closely resembles a tenth century style structure to which a chancel was added two centuries later. The width of the nave is exceptional, and at 9 metres is probably the widest of any of the early Churches in Ireland. The Church ceased to serve as a cathedral when the Diocese of Glendalough was united with Dublin in 1214 AD.
