The Notre-Dame Church was a church in Old Montreal that stood from 1682 until 1830. From 1821 to 1822, it served as the first cathedral of the Diocese of Montreal.

Notre-Dame Basilica (French: Basilique Notre-Dame de Montréal) is a basilica in the historic district of Old Montreal, in Montreal, Quebec, Canada. The church is located at 110 Notre-Dame Street West, at the corner of Saint Sulpice Street. It is located next to the Saint-Sulpice Seminary and faces the Place d'Armes square. The interior of the church is amongst the most dramatic in the world and regarded as a masterpiece of Gothic Revival architecture. The vaults are coloured deep blue and decorated with golden stars, and the rest of the sanctuary is decorated in blues, azures, reds, purples, silver, and gold. It is filled with hundreds of intricate wooden carvings and several religious statues. Unusual for a church, the stained glass windows along the walls of the sanctuary do not depict biblical scenes, but rather scenes from the religious history of Montreal. It also has a Casavant Frères pipe organ, dated 1891, which comprises four keyboards, 92 stops using electromagnetic action and an adjustable combination system, 7000 individual pipes and a pedal board.Approximately 11 million people visit Notre-Dame Basilica every year, making it one of the most visited monuments in North America.

The Aldred Building (French: Édifice Aldred; also known as Édifice La Prévoyance) is an Art deco building on the historic Place d'Armes square in the Old Montreal quarter of Montreal, Quebec, Canada. Completed in 1931, the building was designed by Ernest Isbell Barott, of the firm Barott and Blackader, with a height of 96 metres (316 ft) or 23 storeys. Built at a cost of $2,851,076.00 (equivalent to $47,633,831 in 2020), Barott endeavored to design a modern building which would, at the same time, fit with the square's historic surroundings. The building's setbacks at the 8th, 13th, and 16th floors allow more light on the square and create a cathedral-like massing, reflecting the adjacent Notre-Dame Basilica. The building uses limestone, common to other buildings in the area. The Aldred Building also attempts to address both Place d'Armes and Notre-Dame Street which do not meet at right angles, aligning with both streets until the third floor, where it then steps back and becomes square to Notre-Dame. The odd angle is small and not immediately noticeable from street-level.The building resembles New York's Empire State Building, completed the same year, and was built for Aldred and Company Limited, a New York City-based international finance company.Barott began work on the Aldred Building around 1927, with original design for a building only 12 storeys tall, as building heights were limited to 130 feet (40 m) in Montreal until the passing of a bylaw allowing taller buildings provided they made use of setbacks to reduce their overall mass, similar to one in New York City.Barott was able to take advantage of a 1929 clause in the bylaw that allowed buildings on public squares to exceed the then maximum height by up to 200 feet (61 m), if certain restrictions were adhered to. The building's total floor area is 238,946 square feet (22,198.8 m2).

The Saint-Sulpice Seminary (French:Vieux Séminaire de Saint-Sulpice) is a building in Montreal, Quebec, Canada.

The seminary is a classic U-shaped building featuring a palatial style and includes an annex. Saint-Sulpice Seminary was founded in 1657 by the Society of Priests of Saint Sulpice, who have been the sole owner of the building since its creation. Construction began in 1684 by François Dollier de Casson, superior of the Sulpicians, and was completed in 1687, although later additions, such as the clock, were completed by 1713. It was dedicated to the education of secular priests and to mission work among native peoples in New France.
