The great East Window, known as Ottawa Window, was commissioned in 1916 by Prince Arthur, Duke of Connaught, the third son of Queen Victoria and then Governor-General of Canada, in memory of members of his personal staff who fell in the First World War. The window was commissioned during the war, and there was no guarantee that more officers would not die. So the decision was taken not to include their names in the lower register of the window, but rather to have a separate tablet placed nearby. Those commemorated are recorded on a brass plaque on the north wall of the sanctuary.
It was unveiled by the Prince of Wales, the future King Edward VIII, on 9 November 1919. The window’s creator, Wilhelmina Geddes, was a young artist associated with the avant garde artistic workshop An Tur Gloine (Tower of Glass).
Details on the window include:
Raphael, the Angel of Healing
Gabriel, the Angel of Annunciation
The Angel of Death
The Angel of Peace
Roman Soldier-Saints: Longinus, Sebastian and Martin
Michael, the Militant Archangel
English and French National Saints: Edmund, Joan of Arc, Louis, Saint George
