About the Notre-Dame Cathedral Basilica (Ottawa)
A Roman Catholic minor basilica, Notre-Dame Cathedral Basilica stands on Sussex Drive (number 385), in Ottawa's Lower Town neighborhood, in Ontario, Canada. It has been a National Historic Site of Canada since 1990. It is Ottawa's oldest and largest church and is where the city's Roman Catholic archbishop has his seat. The twin spires and the gilded Madonna are easy to pick out from Parliament Hill and the area around it.
A small wooden church, St. Jacques, built in 1832, first stood on the site. Antoine Robillard, a local builder, and Father John Francis Cannon designed a larger church and asked for a Neo-classical look. The Oblate Fathers (OMI) took charge of the parish in 1844 and brought in Father Pierre-Adrien Telmon from France, who redesigned the church in the Neo-Gothic style. That is why the main entrance and other lower features are Neo-Classical, while the upper parts are Neo-Gothic. Its main structure was finished in 1846, and Pope Leo XIII granted it the status of minor basilica in 1879.
The church has bench seating for 1,544 people, counting the second floor balcony that opens for larger masses. The tin-covered steeples, typical of French-Canadian churches, hold a peal of bells. Outside, the church is fairly restrained, while the interior is richly ornate, brightly painted and filled with carvings, stained glass and hundreds of statues of religious figures. Services are offered in French and in English.
