Christ Church is officially claimed as the seat (cathedra) of both the Church of Ireland and Roman Catholic archbishops of Dublin. In law, and in fact it has been the cathedral of only the Church of Ireland's Archbishop of Dublin, since the English Reformation. Though nominally claimed as his cathedral, the Roman Catholic Archbishop of Dublin uses St Mary's in Marlborough Street in Dublin as his pro-cathedral (acting cathedral)

Christ Church Cathedral is located in the former heart of medieval Dublin, next to Wood Quay at the end of Lord Edward Street. However a major dual carriage-way building scheme around it separated it from the original medieval street pattern which once surrounded it, with its original architectural context (at the centre of a maze of small buildings and streets) lost due to road-building and the demolition of the older residential quarter at Wood Quay. As a result the cathedral now appears dominant in isolation behind new civil offices along the quays, out of its original medieval context. Wikipedia
