Center Line: the whole city sits inside Warren

Draw Center Line on a map and you’ve drawn a small square island. Every road that leaves it crosses into Warren, because Warren wraps the whole city — all roughly 1.7 square miles of it — on every side. It’s its own city government, its own schools, its own police, entirely landlocked by another town.

The name came long before any of that. The story goes that the area sat on the middle of three old Native American trails running north out of Detroit toward the trading posts, and the one through here was the “center line.” In the mid-1800s the crossroads was known as Kunrod’s Corner, and a German Catholic community grew up around St. Clement Church, built in 1854 so settlers wouldn’t have to walk all the way to a Detroit parish for Sunday Mass.

The reason Center Line ended up an island is a quirk of timing. It incorporated as a village in 1925, voters approving the charter that November, and stepped up to a full city in 1936. The farmland all around it was Warren Township — which kept growing, then incorporated as the city of Warren in the 1950s, expanding outward until it had completely encircled the older, smaller community that had jumped first.

So Center Line never moved; everything around it did. It’s a tidy lesson in how Michigan’s patchwork of cities and townships actually formed — whoever incorporated earliest got to keep their lines, and the latecomers had to build around them. Drive Van Dyke straight through and you cross from Warren into Center Line and back into Warren in the space of a few minutes, usually without noticing the borders at all.
