The back part of the sanctuary forms an hemicycle surrounded by a 6-foot wide circumambulatory. The sanctuary itself is 48 feet wide and 70 feet deep. The main altar stands at the front of the sanctuary and the stalls of white oak are on both sides of the altar and of the hemicycle. The throne is placed on the left hand side. It could also be placed to the rear of the apse, like in the roman basilicas. All around the cathedral, beginning in the sanctuary, there runs a frieze displaying in classical lettering the following invocations in French : « Our Lady of Sherbrooke, Queen of the Eastern Townships, pray for us, give us salvation and peace. » Beginning under the central main stained glass window : « St. Michael the Archangel, protect us in battle, be our proctector against wickedness (continuing along the right nave) and the malice of the devil. May God rule him, we beseech you, and you, Prince of the heavenly armies, with the divine power bestowed on you, drive into the dephts of hell Satan and all other evil spirits roaming the earth to cause the loss of souls. » Beginning under the organ balcony, continuing along the left nave and ending in the north transept : « St. Michael, the Archangel, pray for us, great defender of the Christian family, defeat heresies, confound incredulity. Most glorious prince, herald the divine glory, grant us final perseverance. Protect us from all dangers so that we may not perish in the day of judgement. » Source : La Basilique-Cathédrale Saint-Michel de Sherbrooke, Brother Gérard Brassard, A.A., 1967, page 36.
