If you’re standing on the Detroit Riverfront and look up, it’s hard to miss the massive glass cylinders reflecting the water. That’s the Renaissance Center, or the RenCen if you want to sound like a local. For nearly 50 years, this sprawling complex has been the undisputed heavyweight champion of the skyline. Specifically, the central tower—the Detroit Marriott at the Renaissance Center—is the tallest building in Michigan.
It stands 727 feet tall. If you count the antenna, it reaches about 750 feet. It’s got 73 floors of hotel rooms, spinning restaurants, and views that make Windsor, Ontario, look like a scale model.
But things are getting weird in Detroit. There’s a new kid on the block that everyone thought was going to steal the trophy. If you’ve been following the construction at the old J.L. Hudson’s site on Woodward Avenue, you know exactly what I’m talking about. Hudson’s Detroit has been the talk of the town for years, and for a minute there, it looked like it was going to be the new tallest building in Michigan.
Spoiler alert: it didn't quite make it.
The Battle for the Sky: RenCen vs. Hudson's Detroit
Honestly, the height drama surrounding the new Hudson’s building was a bit of a roller coaster. Back when Bedrock (Dan Gilbert’s real estate firm) first announced the project, the plans were ambitious. Like, really ambitious. At one point, they were talking about a tower reaching 912 feet. That would have crushed the RenCen.
Then the plans changed. Then they changed again.
As of early 2026, the Hudson’s Detroit tower is topped out and basically finished on the outside. It stands at 685.4 feet. It’s massive, and it’s the first building over 500 feet built in the city since the 90s, but it remains the second-tallest building in Michigan.
Why the RenCen is still a big deal
The Renaissance Center isn't just one building; it’s a fortress. It has its own zip code (48243). It was designed by John Portman in the 70s as a "city within a city," which, fun fact, basically meant it was designed to be so self-contained that people wouldn't have to leave it to go into the rest of downtown Detroit.
- Height: 727 feet (Marriott Tower).
- Floor Count: 73.
- Total Area: Over 5.5 million square feet.
- Vibe: Very "80s sci-fi," but in a cool, imposing way.
Even though it’s still the tallest building in Michigan, its future is kinda up in the air. General Motors, which has owned the place for decades, is officially moving its headquarters. Where are they going? Ironically, they’re moving into the Hudson’s Detroit complex. This leaves the RenCen in a weird spot. There’s even been talk of tearing down some of the smaller towers to make the site more "accessible" to the rest of the city.
The Rest of the Giants: Michigan's Top 5
Most people assume all the tall stuff is in Detroit, and... well, they're right. If you look at the top of the list for the tallest building in Michigan, you have to scroll down a long way before you see a city that isn't Detroit.
1. Detroit Marriott at the Renaissance Center (Detroit)
The king. 727 feet. It’s been at the top since 1977.
2. Hudson’s Detroit (Detroit)
The newcomer. 685 feet. Even though it's shorter than the RenCen, it feels "newer" and more integrated into the city's walkable core. It’s got that sleek, modern SHoP Architects look.
3. Ally Detroit Center (Detroit)
Standing 619 feet tall. You might remember it as One Detroit Center. It’s that gothic-looking skyscraper with the spires on top. For a long time, this was the tallest office building in the state.
4. Penobscot Building (Detroit)
This one is a classic. 565 feet. Built in 1928. It was the tallest building in Michigan for decades until the RenCen showed up. It’s got that beautiful Art Deco style and a giant red orb on top that glows at night.
5. Renaissance Center Towers 100, 200, 300, 400
These are the four office towers that surround the big Marriott tower. They all stand exactly 522 feet tall. They're like the Marriott's bodyguards.
What about outside Detroit?
If you’re wondering about the tallest building in Michigan that isn't in Detroit, you have to head over to the west side of the state. The River House Condominiums in Grand Rapids takes that title. It stands at 406 feet. It’s a nice building, but it would only be about the 16th tallest if it were in Detroit.
Why We Care About Vertical Limits
You might think height is just a vanity project for developers. Sorta is. But in Detroit, these buildings represent different eras of the city’s soul.
The Penobscot represents the "Paris of the West" era, when Detroit was the richest city in the world. The RenCen represents the "Urban Renewal" era—a gritty, concrete attempt to stay relevant during a decline. And Hudson’s Detroit? That represents the "Comeback."
The fact that the tallest building in Michigan is no longer just a lonely outpost on the river, but part of a cluster of new development, says a lot about where the city is headed.
Surprising Facts about Michigan's Skyscrapers
- The Demolition Record: The old Hudson’s department store (which sat where the new tower is now) was 440 feet tall. When it was imploded in 1998, it set a world record for the tallest building ever demolished by controlled implosion.
- The Bridge Factor: Believe it or not, the tallest structure in Michigan isn't a building at all. It’s often a radio tower or, lately, the towers of the Gordie Howe International Bridge. The bridge towers hit 722 feet, which is almost as tall as the RenCen.
- The "Hole" in the Ground: For nearly 20 years, the site of the new Hudson's building was just a giant empty pit. People called it "Hudson's Hole." Seeing a 685-foot skyscraper there now is still a bit of a shock for long-time residents.
What’s Next for the Michigan Skyline?
If you’re planning a visit to see the tallest building in Michigan, 2026 is actually a pretty interesting time to do it. The Hudson’s Detroit office building is already open, and the main tower is finishing up its interior work.
You can walk through the new "Nick Gilbert Way" plaza that cuts through the Hudson's site. It connects Woodward to Farmer Street and makes the whole area feel alive. Meanwhile, at the RenCen, the Marriott is still open for business, but the surrounding office towers are transitioning as GM packs its boxes.
If you want the best view of these giants, don't just stay on the ground. Head to the Highlands restaurant at the top of the RenCen for a drink. You’ll be looking down at the rest of the state. Or, wait for the Detroit Edition hotel to open in the Hudson’s tower later this year for a perspective of the city that didn't exist two years ago.
Actionable Insights for Your Visit:
- Park at the Z-Lot: If you're visiting the Hudson's site, this nearby garage is basically an outdoor art gallery.
- Check the Riverwalk: The best way to photograph the RenCen's scale is from the Dequindre Cut entrance or the Cullen Plaza.
- Verify Restaurant Hours: Places like the Highlands in the RenCen often require reservations weeks in advance because of the "tallest building" novelty.
- Use the People Mover: It’s cheap (actually free for most of 2024-2025) and gives you a great mid-level view of the architecture as you loop through downtown.
The skyline is changing fast, but for now, the Renaissance Center keeps its crown. It might be aging, and its biggest tenant might be leaving, but 727 feet is still the number to beat.
