The episcopal seat of the Roman Catholic Archdiocese of Winnipeg, St. Mary’s Cathedral stands as a landmark of Romanesque revival architecture in downtown Winnipeg, serving as one of two major Catholic cathedrals in the city.
At a glance
St. Mary’s Cathedral occupies a prominent corner site at Saint Mary Avenue and Hargrave Street in Winnipeg’s downtown core. It functions as the principal church of the Roman Catholic Archdiocese and remains a well-known municipal historic landmark. The cathedral shares its role as a Catholic center of worship with St. Boniface Cathedral, which lies across the Red River in the former city of Saint Boniface.
History
The cathedral was originally designed in 1880 by C. Balston Kenway. In 1896, the building underwent significant updates by Samuel Hooper, an English-born stonemason and architect who went on to serve as Provincial Architect of Manitoba. These interventions shaped the structure we see today.
What you see
The building combines Romanesque revival and Germanic architectural elements. Its distinctive stained glass has been documented by the Institute for Stained Glass in Canada, representing an important component of the cathedral’s aesthetic and spiritual character.
Cultural significance
As one of the few churches remaining in Winnipeg’s downtown district, St. Mary’s Cathedral holds particular cultural weight in the urban landscape. The cathedral represents both Catholic heritage and the city’s architectural history, bridging 19th-century design traditions with municipal identity.
