As you know, St. Patrick is the patron Saint of Ireland, and it really is popularly revered and beloved Holy. It is not surprising that the largest Church of Ireland and one of the oldest temples on the island bears the name of Saint Patrick's day. The official name of the Cathedral is the national Cathedral and Collegiate Church of Saint Patrick in Dublin. It should be noted that, although the Cathedral is the Cathedral, the chair of the Bishop is in the Cathedral of Christ. Two Cathedral in the same city is a unique phenomenon, and quite a while they remained in a constant state of rivalry. In 1300 it was agreed to the separation of powers, by which, for example, the cross, the mitre and the ring of the late Archbishop should be kept in the Cathedral of Christ, and burial of bishops should be held alternately in both cathedrals; in General, the two cathedrals should work together on an equal footing. In 1870 the St. Patrick's Cathedral was given the status of national, and the seat of the chair of the Dublin Bishop was defined as the Cathedral of Christ.

In 1192, the Archbishop of Dublin was named one of the four churches of Dublin the status of a collegiate Church. It was St. Patrick's Church, built near the source, bearing the name of this Saint. When the Church received the status of a Cathedral is not exactly known, probably in the early thirteenth century. From the original Church of the XII century, now almost nothing left. The main buildings of the XIII-XIV centuries made in the style of early English Gothic. Later the Cathedral was repeatedly rebuilt, and its walls were strengthened. The fact is that due to the proximity of the river Poddle and its many distributaries, the walls of the Cathedral are constantly otaplivayutsya, as sometimes happened and floods, the water level in the building could be up to two meters. For this reason, in the Cathedral no basements, no crypts.

In the XIV century was built the tower of the Cathedral, in 1769 it was installed on the spire, and the total height of the tower is 140 m.
