herr2ck: Nine to Yo Dome

August 2025.

St. Joseph’s Oratory is one of the best-known churches in Montreal and Canada at large, considering that it is both Canada’s largest church and has one of the largest church domes in the world, behind only St. Peter’s Basilica in Rome. Its massive scale and contrasting styles (Renaissance Revival exterior versus Art Deco interior) suit its status as a minor basilica and national shrine.

St. Joseph’s Oratory is located at 3800 Chemin Queen-Mary in the Cote-des-Neiges neighborhood of Montreal, Quebec. It is bordered by Mount Royal and single-family homes to the east and Chemin Queen Mary and Notre-Dame College to the west.

History

The story of St. Joseph’s Oratory begins with Saint Andre Bessette (better known as Brother Andre), a monk in the Congregation of Holy Cross. Brother Andre was orphaned at the age of 12, being confirmed that year and briefly attending school before working various jobs in Saint-Cesaire, Quebec and Moosup, Connecticut. Upon returning to Canada, he was accepted to the Congregation of Holy Cross after recommendation by his church’s pastor, and he made his final vows at age 28 in 1874. Brother Andre became the monastery’s porter (the monk who interacts with the public) and worked at Notre-Dame College, which is just west of St. Joseph’s Oratory’s site today. He began to minister to the sick, eventually gaining a reputation as a miracle healer, as people claimed to be cured through Brother Andre and St. Joseph’s prayers.

With Brother Andre’s growing reputation and his own admiration for St. Joseph, he sought to honor the saint more, and in 1904 he requested funding for a small chapel that would venerate St. Joseph. The congregation approved its construction, and the Gothic Revival structure was completed that year. This little chapel expanded four times during its lifetime, and coupled with Brother Andre’s ever-increasing fame (he was actually asked to leave Notre-Dame College and minister to the sick in a nearby train station), Congregation of Holy Cross again accepted his request to build a larger basilica.

St. Joseph’s Oratory’s first phase was designed by architects Dalbe Viau and Alphonse Venne, who had worked for the Congregation of Holy Cross in the past. Its construction officially began in 1914, which started with the crypt church. The crypt church was completed in 1916, and some of the remaining portions of the crypt and church above were completed between 1924 and 1930. Viau and Venne had designed a smaller dome similar to Michelangelo’s famous design atop St. Peter’s Basilica, but their plans were halted due to the Great Depression in 1931. This left the church mostly complete but missing its dome.

Alphonse Venne died in 1934, and in 1937 Paul Bellot was hired to replace him, though Bellot had to work with Lucien Parent since the former was not a licensed architect in Canada. Bellot’s design for the dome was inspired by Florence Cathedral’s octagonal dome and at a much larger scale. The dome and roof were completed in 1941. Some interior renovations occurred between 1949 and 1951 by architect Gilbert Moreau. The first Mass inside was celebrated in November 1954, and the oratory was made a minor basilica in March 1955. Its official opening was in 1956, though the interior was not fully completed until 1967.

Brother Andre was beatified in 1982 and canonized in 2010. His church was made a National Historic Site of Canada in 2004.

The most recent change to the oratory was a renovation of the dome and observatory, as well as the construction of a contemporary welcome center. This work began in 2018 by firms Atelier TAG and Architecture49. When I visited in August 2025, this work seemed to be finished, but the crypt church’s stained glass was under restoration.

We’ll actually start with Brother Andre’s 1904 chapel, which is located south of the oratory today but was originally on its site:

The chapel is small and much of its later additions were removed over its two moves. It is a very restrained Gothic Revival design, and the only elements suggesting that style are the corner buttresses and cupola on top. The windows are not pointed, however.

The first floor has a pretty fancy altar compared to the humble exterior:

Note St. Joseph at center, surrounded by two angels on the altar itself and Mary and Jesus on either side of it. There’s also discarded crutches on both walls, undoubtedly in reference to Brother Andre’s supposed healing abilities. I like the various stone tablets hung on the walls.

I liked the plaster pattern on the walls, too:

The second floor had Brother Andre’s living quarters, but it was too cramped to photograph properly. It was likewise humble and small, suitable for a monk’s vows.

Now, let’s rewind back to ground level. The oratory looms over its surroundings, aided by its placement on the hill:

I do hate the gigantic parking lots to the west and south of the church, though. Such a uniquely (North?) American feature. Important cultural heritage becomes watered down to a strip mall or amusement park. I understand the need for parking at such a famous tourist destination, but unless it’s really out of the way, it always undermines the buildings’ effect.

Looking at the church more frontally from the stairs:

A lot of Viau and Venne’s Renaissance “glop” (as my architectural history professor would have called it) was shucked off the final product, and the end result is a simpler, almost Stripped Classical, design. The wall plane of the crypt is mostly flat, only interrupted by large keystones and little shields between the bays. The only other visual detail at this level is the random bond of the masonry.

An interesting tidbit is that the wooden stairs at middle, with the signs in front, are intended for pilgrims who climb all of the steps to the oratory on their knees (since there are a lot of stairs). I know sacrifice is a pretty big thing in Catholic theology, but that seems a little extreme to me. I don’t remember seeing anyone do that while I visited.

**In the coming interior photos of the crypt and later the oratory, you will notice an orangeish tint. My camera’s light balance at the time was calibrated to a gray card in neon purple lighting for an old photography class project, which I failed to reset afterwards. I only noticed this discrepancy and rectified it months later.

Inside the crypt church designed by Viau and Venne:

This is probably the most orthodox Renaissance area of the interior. The crypt church consists of a long nave with a shallowly vaulted ceiling, having several small bays on either side and an apse at the end with a statue of St. Joseph.

This photo of a vault rib aims to highlight a couple things:

At center is a Station of the Cross, specifically Jesus meeting the women of Jerusalem. It is lit by a cool antique light fixture, which is hung from a decorated plaster panel. Again, most of the crypt church’s interior is sparsely ornamented, and these ribs feature the most rich applied ornamentation.

One of the bays, featuring a stained-glass window and a confessional below:

The central window is not supposed to be dark, it is boarded up since they were undergoing restoration when I visited.

The apse is also pretty fancily decorated:

At center is a statue of St. Joseph with baby Jesus and a crazy golden sunburst behind. The circular apse is lined with wooden wainscoting and windows above. The shallow dome shape and deeply punched windows kinda remind me of a Byzantine dome.

The organ and entrance behind me:

More beautiful woodwork here, too. I like the light fixture with metal angels on it:

Here is the exterior from the porch above the crypt:

The main entrance is at center, with its four Corinthian columns supporting an entablature above. Two cross decorations sit below the pediment, which features modillions and a shield reading “St. Joseph.”

Note that the frieze reads the church’s name:

A closer look at the entrance and its columns:

The south end of the oratory, from the nearby parking lot:

The transept is at center, featuring its pediment and rose window. An entablature with pilasters sits beneath. It is surrounded by two intermediate towers with metal crowns. The large copper dome rises above, centered on the crossing.

Zoomed in on the transept:

Again, most of this building’s effect is dependent on its bold massing and expression, rather than smaller-scale ornamentation. There is a cornice along the base, and the transept is crowned with a Corinthian pediment, as well as some small swags and a shield in the middle. The main center of attention on the transept is its rose window, which has a typical classical arch shape but unusually melds it with abstracted Gothic tracery. The dome’s shaft above has masonry details such as a band of piers along its top, too.

Green oxidized copper is a lot different than red tiles:

The Art Deco nave:

This is a much different effect than the oratory’s exterior, as it achieves its sense of power through abstraction, form, and light alone rather than crazy ornamentation. It represents architecture’s change in sensibility from applied decoration to a more tectonic ideal in the time of Modern architecture. Don’t get me wrong, this is a far cry from orthodox Mid-Century Modern churches, but it is likewise far from a Gothic cathedral too.

Zoomed in on the altar and apse behind:

Vaulting is simply suggested through the almost pixelated nature of the arched portals, and the ceiling is looser and more textured than the regular groin vaulting of a Renaissance or Gothic nave. The organization is still there, but the church is expressed differently.

The fancy light fixture above the altar dates to a more recent renovation:

Even the dome’s interior uses a smooth tessellation of geometric shapes to add texture, rather than coffers:

A better look:

The base is lined with clerestory windows, and the dome continues upwards. It is constructed using the “double-shell” method that many other large domes employ, where the exterior and interior of the dome appear different due to the fact they are discrete parts. Apparently, the interior “shell” is only five inches thick.

Looking at the north transept:

No chapels or grand entrance here, just a semicircular rose window. Note that it is concentric with the surrounding vault.

One of the stained-glass windows, with a more regular interpretation of Gothic tracery:

Even the statues employ a more abstract form than classical or Gothic sculpture:

I think this is off the south transept, but here you can see how lighting helps the interior achieve its architectural effect:

A fixture above this little alcove floods the top in light, which gradually diffuses downwards. This emphasizes this area more from its darker surroundings.
