greatly to the exterior impact of the building, and the aisle roofs were raised accordingly, permitting the insertion of a triforium below the clerestory. A sense of drama was added to the transepts by the addition of asymerical spired turrets to their ends and the addition of rose windows to their gables. The most dramatic change effected to Duff's plans was the abandonment of the three rather squat towers designed by Duff to reach a height of . Instead, two breached towers crowned with spires high were constructed at the West end. Dixon died in 1866 again before the completion of the cathedral and once again the project was abandoned under his elderly successor Archbishop Michael Kieran. It thus fell to Kieran's successor, Archbishop Daniel McGettigan to complete the building. Following the completion of the spires, McGettigan turned his attention to the interior. Here, to capitalise on the increased height gained at the expense of external massing, McCarthy constructed an elaborately carved vaulted hammer-beam roof with carved angels terminating the hammer beams and stone saints as corbels. He designed a Caen stone reredos which spans the entire wall of the east end and which is filled with carvings from the life of the Virgin below an arcade of carved and crocketted pinnacles and centered with a carved canopy over a statue of the Madonna and Child. Archbishop McGettigan commissioned painted murals to adorn the walls of the Lady Chapel and stencilling was applied to its ceiling. The cathedral was dedicated on 24 August 1873. Following the dedication, Primate McGettigan continued to make improvements as funds and his declining health would allow. In 1875, he commissioned the Stations of the Cross from Herbert & Co. of Liverpool and installed the Great 33-stop pipe organ by William Telford. In 1879, the seven-light east window was filled with stained glass by Earley & Powell of Dublin and work began on the seven terrace flight of steps to the plaza in front of the west end. Finally in 1884, a sacristan's lodge was constructed at the bottom of the steps. When Archbishop McGettigan died in December 1887 after some years of failing health, the cathedral had seen the passing of five successive Archbishops and the expenditure of the unprecedented sum of over £70,000. The cathedral of Cardinal Logue McGettigan's successor as Archbishop was Michael Logue, longest serving Archbishop of Armagh. A famously learned cleric,
