I've been selling real estate in Detroit since 2005, and I still find myself surprised by this city. Every corner of it holds a story most people haven't heard — layers of invention, music, architecture, and pure audacity that don't make the highlight reel. If you think you know Detroit, these facts might make you reconsider what you know.
Key Takeaways
- Detroit is the only major U.S. city where you look south to see Canada, making it geographically one-of-a-kind on the continent.
- The "I Have a Dream" speech debuted in Detroit before it was delivered at the March on Washington — the city's civil rights legacy runs deep.
- More than 100 miles of road run beneath the city's streets, inside a working salt mine that's been operating for well over a century.
- Detroit is the birthplace of Vernors Ginger Ale, the oldest surviving soft drink in the United States, invented right here in 1866.
Detroit Is the Only Major U.S. City Where You Look South Into Canada
A geographic quirk worth knowing:
- Windsor, Ontario sits directly south of downtown Detroit across the Detroit River.
- The Ambassador Bridge and the Detroit-Windsor Tunnel are among the busiest border crossings on the continent, connecting two countries that share one of the world's largest trading relationships.
- Standing at the riverfront and gazing south into another country is a reminder of just how singular Detroit's position is — not just in Michigan, but in all of North America.
It also explains why, during Prohibition, Detroit was strategically positioned to move more illegal liquor than almost any other city in the country. With legal alcohol just across the river in Windsor, an estimated 75 percent of all bootlegged spirits flowing into the U.S. passed through here. The city's location has always been an asset.
Martin Luther King Jr. Gave His Most Famous Speech Here First
Before Washington, there was Detroit:
- In June 1963, Dr. King delivered a version of what would become the "I Have a Dream" speech during the Detroit Walk to Freedom along Woodward Avenue — weeks before the March on Washington.
- An estimated 125,000 people participated in that march, making it one of the largest civil rights demonstrations in American history at the time.
- That history is woven into the streets I walk every day, and it's one reason Detroit's cultural identity runs so much deeper than cars and Motown.
The city has always been a place where big things happen first. It was home to the first mile of concrete road in the country, laid on Woodward Avenue in 1909. It produced the first four-way traffic light. The first urban freeway in the United States, the Davison Freeway, was built here in 1942. Detroit doesn't follow trends. It starts them.
There Are Over 100 Miles of Road Under the City
Detroit's underground salt mine is an engineering marvel:
- About 1,200 feet beneath the streets of Detroit, the Detroit Salt Company operates a working salt mine with more than 100 miles of roads carved through it.
- The mine covers roughly 1,400 acres and has been in operation since the late 1800s, supplying road salt to municipalities across the Midwest.
- Most people living above it have no idea it exists.
It's the kind of fact that changes the way you think about a city. Detroit has always operated at multiple layers — literally and figuratively. From the underground infrastructure to the hidden architectural gems like the Guardian Building's Art Deco lobby and the Pewabic tile throughout the city's historic schools and public buildings, there is always more to discover here than what's visible from the surface.
Vernors Was Invented in Detroit — and It's the Oldest Soda in the U.S.
Detroit pharmacist James Vernor created it in 1866:
- According to local history, Vernor mixed a new ginger-flavored beverage before leaving to serve in the Civil War. When he returned, he found the drink had been transformed by four years of aging in an oak cask — giving it the distinctively bold, spicy character Detroiters still swear by.
- Mixing Vernors with vanilla ice cream creates a Boston Cooler — named after Boston Boulevard in Detroit, not the Massachusetts city.
- The drink has been a local staple for more than 150 years and remains one of the most recognizable regional beverages in the country.
It's a small thing, but it says a lot about Detroit. The city takes pride in what it makes and holds onto it. That same spirit shows up in the neighborhoods — in the meticulous restoration of Boston-Edison homes, in the care people bring to Lafayette Park mid-centuries, in the families who have stayed in Sherwood Forest and Palmer Woods for generations.
The J.W. Westcott II Has Its Own ZIP Code
America's only floating post office operates on the Detroit River:
- The J.W. Westcott II is a mail boat that has been delivering correspondence to passing ships on the Detroit River since 1874.
- It is the only vessel in the United States with its own ZIP code: 48222.
- The boat delivers mail, parts, and supplies to freighters in motion — pulling alongside massive cargo ships without either vessel stopping.
Spend enough time in this city and you start to understand that Detroit has always found creative solutions to unusual problems. That ingenuity is part of what makes the real estate here so compelling. The people who built these neighborhoods, these institutions, and these traditions were not ordinary. And the city they left behind reflects that.
