The Chicago Municipal Device: A Six-Pointed Star That Tells the City’s Story

Today, Chicago adds another candle to the cake. Incorporated on March 4, 1837, the city officially became a municipality, trading muddy frontier boots for civic ambition. And what better emblem to toast than the Chicago Municipal Device, the six-pointed star that quietly signs the city’s name on steel, stone, and story?

If Chicago had a signature flourish, this would be it.

What Is the Chicago Municipal Device?

The Chicago Municipal Device is the official corporate symbol of the City of Chicago, adopted in 1917. At its center is a Y-shaped figure representing the three branches of the Chicago River. Around it radiate six points, each marking a defining era in the city’s development.

It is often confused with the four red stars on the Flag of Chicago, but the two serve different purposes. The flag flies. The Municipal Device authorizes. One waves in the wind. The other is bolted into the bones of the city.

Why It Matters, Especially Today?

On Chicago’s birthday, the Municipal Device feels less like a design and more like a time capsule you can step on.

It is cast into iron on bridges that span the river it represents. It is pressed into the sidewalks that carry commuters and dreamers. It is stitched onto uniforms worn by those who keep the city moving.

For a place that survived fire, economic upheaval, and reinvention after reinvention, the six-pointed star is not decorative. It is declarative.

Happy birthday, Chicago. Your symbol still shines.
