 In 1924 it was decided to build the west front of the cathedral as a memorial to the Ulstermen and women who had served and died in the Great War.The foundation stone for this was laid by The 3rd Duke of Abercorn, Governor of Northern Ireland, on 2 June 1925 and the completed facade, to an amended design by the architect Sir Charles Archibald Nicholson, was dedicated in June 1927.In the meantime, the central crossing, in which the choir sits, was built between 1922 and 1924.
