You see it from I-75. Those twin spires piercing the Detroit skyline at 217 feet. If you’re driving past the Forest Park neighborhood, Sweetest Heart of Mary Detroit looks less like a local parish and more like a European cathedral that got air-dropped into the Motor City. It is massive. It is red. And honestly, it shouldn’t even be standing today.
Most people see the brick and the stained glass and think "old church." But "Hearts," as the locals call it, is a monument to a full-blown rebellion. It’s a story of an outcast priest, thousands of immigrants who mortgaged their own homes to save a building, and a set of windows so beautiful they literally won awards at the 1893 World’s Fair.
The Priest Who Said "No" to the Bishop
The history of Sweetest Heart of Mary Detroit starts with a guy named Father Dominic Hippolytus Kolasinski. He was charismatic. He was also incredibly stubborn. In the late 1880s, Detroit’s Polish community was exploding, but they felt like second-class citizens in German-run parishes. Kolasinski became their champion.
After a messy dispute with the local bishop that involved a suspension and a temporary move to Dakota, Kolasinski came back to Detroit in 1888. He didn’t ask for permission. He just started his own parish outside the official jurisdiction of the Catholic Church.
People loved him. They called themselves "Kolasinskians."
By 1890, they started building the current structure on Russell Street. They didn't have corporate sponsors or a massive endowment. They had laborers. Thousands of Polish immigrants who spent their days in Detroit’s factories and their nights and weekends building a Gothic Revival masterpiece. It cost $125,000 back then. That sounds like a bargain now, but in the 1890s? That was a staggering amount of money for a community of immigrants.

A Near-Death Experience for the Parish
Here’s the part people usually forget: the church was almost auctioned off.
The Panic of 1893—basically a massive economic depression—hit right as the church was finishing up. The parish went into debt. They couldn't pay the bills. The building was actually sold at auction for a measly $30,000.
Imagine that. You build the largest Catholic church in Michigan, and the bank takes it.
But the "Kolasinskians" weren't having it. In a move that defines Detroit’s "hustle harder" spirit a century before it was a bumper sticker, the parishioners stepped up. Families literally mortgaged their small, simple homes to raise the cash. They secured a loan through a Canadian branch of the Bank of England and "repurchased" their own church for $45,000.
Eventually, the Vatican stepped in. They told the Detroit Bishop to make peace. On February 18, 1894, Kolasinski and his flock were officially brought back into the fold, and the church's name was tweaked to Sweetest Heart of Mary.

Why the Architecture is Actually a Big Deal
The building is a Late Victorian Gothic beast. Designed by the firm Spier & Rohns, it’s built in a cruciform shape (like a cross) with red brick and rusticated stone. But the real magic happens when you step inside and the sun is out.
Those Famous Stained Glass Windows
You’ve probably heard of the 1893 World’s Columbian Exposition in Chicago. It was the "White City" that changed American architecture. Well, the windows in Sweetest Heart of Mary Detroit were there.
Created by the Detroit Stained Glass Works, these aren't just colored panes. They are massive narrative pieces. The "Holy Family" window in particular won a major award at the World's Fair before being installed in the church.
- The North transept features Saint Vincent de Paul.
- The South transept shows Jesus working in a carpenter shop.
- There are 101 stained glass windows in total.
The Oldest Electric Organ in Michigan
If you’re a gear-head or a music nerd, the organ is the highlight. It’s an 1893 Austin Organ, Opus No. 2. It’s not just old; it’s the oldest Austin organ still in service anywhere. It was also the first electro-pneumatic organ in the state. When that thing starts up during a service or the annual festival, you don’t just hear it. You feel it in your teeth.
The Pierogi Festival and Modern Life
Detroit has changed. The neighborhood around Russell and Canfield isn’t the dense Polish enclave it was in 1920 when the school had 1,500 students. Today, the church is part of the Mother of Divine Mercy Parish, having merged with St. Josaphat in 2013.

But once a year, the "Sercowo" (The Heart’s Area) vibe comes back in full force.
The Sweetest Heart of Mary Pierogi Festival is usually the second weekend of August. It’s the largest religious festival in the city. You get the "Polka Mass," the Tatry Dancers, and more pierogi than you can reasonably eat in a lifetime. It’s one of the few times a year you can see the church filled to the rafters, just like it was back in Kolasinski’s day.
How to Visit and What to Look For
If you’re planning to visit, don't just snap a photo of the outside and leave. You’ve gotta get inside.
- Check the Mass Schedule: The church is most vibrant during the 10:00 AM Sunday Mass. It's often a "Polka Mass" during the festival, but even on a regular Sunday, the acoustics are incredible.
- Look Up at the Ceiling: The 88-foot-tall nave features intricate mosaic work and dozen-plus glass chandeliers that look like they belong in a palace.
- Find the Bells: The two towers hold three massive bells named St. Mary, St. Joseph, and St. Barbara. They still ring, a sound that has echoed through the East Side for over 130 years.
- The "Old School" Building: Walk behind the church. You’ll see the original school/parish hall built in 1889. It’s a reminder of how this community started from practically nothing.
Sweetest Heart of Mary Detroit isn't just a relic. It’s a survivor. It survived the Panic of 1893, the Great Depression, the 1967 rebellion, and the city’s bankruptcy. It stands as a testament to what happens when a community refuses to let their heritage be sold to the highest bidder.
To truly experience the history, time your visit for the Pierogi Festival in August. If you're going for the architecture, aim for a bright Saturday afternoon when the sun hits the West-facing windows. You can also contact the parish office at 313-831-6659 to see if they have any scheduled tours or "Mass Mob" events coming up, as these provide the deepest dive into the "Preserving Sweetest Heart" restoration efforts currently underway.
