The 12 Oldest Established Cities in Michigan

If someone asked you to name Michigan's oldest city, there's a pretty good chance you'd say Detroit. It's a reasonable guess. Detroit has been the state's biggest and most influential city for generations. But when it comes to age, Detroit doesn't actually take the top spot. That honor belongs to Sault Ste. Marie according to Oldest.org. A fact I learned last weekend during my first visit to the northern end of I-75 in the U.S.

The Upper Peninsula's Role in Michigan History

Located in Michigan's Upper Peninsula along the St. Mary's River, Sault Ste. Marie was established in 1668, making it not only Michigan's oldest city but also one of the oldest continuously inhabited European settlements in the United States.

In fact, Michigan's earliest history wasn't centered in Detroit at all. Long before the Lower Peninsula became heavily populated, French explorers, missionaries, and fur traders were building communities throughout the Upper Peninsula and along key Great Lakes waterways.

Why Detroit Isn't Michigan's Oldest City

Detroit came next in 1701 when French explorer Antoine de la Mothe Cadillac established Fort Pontchartrain du Détroit according to our sister station, WFMK. The city would eventually grow into Michigan's economic and cultural powerhouse, but it wasn't the first.

Other communities that rank among Michigan's oldest established cities include St. Ignace, Monroe, Mackinac Island, Niles, Pontiac, Ann Arbor, Ypsilanti, Tecumseh, Adrian, and Marshall. Many of these locations began as trading posts, military outposts, transportation hubs, or centers for early settlers moving westward through the territory.

Cities Established Before Michigan Became a State

What's fascinating is that several of these cities were already thriving communities long before Michigan officially became the 26th state in 1837.

Of course, it's important to remember that Indigenous peoples lived throughout Michigan for thousands of years before any European settlement was established. Communities belonging to the Ojibwa, Ottawa, Potawatomi, Huron-Wendat, and other nations formed the foundation of Michigan's earliest history.

How These Historic Communities Shaped Michigan

Today, these cities continue to serve as living reminders of the state's past. Whether it's the historic streets of Detroit, the waterfront views of Monroe, or the centuries-old roots of Sault Ste. Marie, each tells a different chapter in the story of Michigan.

So if somebody asks you what Michigan's oldest city is, you've got the answer. And it's not Detroit.
