The Notre Dame Basilica in Montreal.
Founded in 1642, the original parish was a wooden church which lasted until 1659. Operated by the Jesuits until the arrival of the Sulpicains in 1657. The original stone church's construction was started in 1672 to 1683. By the 1800s however the parishioners would no longer fit inside the stone church. So in 1823 the approval for reconstruction was passed. The parish brought in James O'Donnell from New York, and construction of the towers commenced in 1841. The western tower holds a single great bell, while the eastern contains a carillon of 10 bells.
Between 1866 and 1882, Father Benjamin-Victor Rousselot supervised the beautification of the sanctuary. Inspiration was drawn from the Sainte-Chapelle in Paris. For the project architect Victor Bourgeau was hired. Work was started in 1874 and was completed by 1880
The sculptures were created by Henri Bouriche. The entire piece was centered around illustrating the Eucharist, or rather Christ's Sacrifice. It also houses three reliquaries.
Designed and built by the famous Casavant brothers of Saint-Hyacinthe it was built and installed in 1891. It has been upgraded and modified several times. Currently it has 4 keyboards, 99 stops, and approximately 7,000 pipes.
Built between 1888 and 1891 according to plans found, it was almost completely destroyed by a fire on Dec 7th, 1978. Between 1979 and 1982 it was rebuilt. The front is a massive sculpture in bronze symbolizing our march towards the Holy Trinity (Father, Son, and Holy Spirit).
