St. Patrick’s Day Tradition: Chicago River Turns Green

While rivers usually change colors due to natural factors like algae or geological events, the Chicago River is a notable exception. Each year, as a St. Patrick’s Day tradition, the city of Chicago chooses to dye its famous river green to celebrate the holiday. You might have witnessed this spectacle firsthand, but viewing it from a distance certainly enhances its visual impact.

Ironically, Chicago’s Irish population constitutes only 7.5% of the city’s demographic. Still, given that both the Irish community and the city itself share a similar age, this playful tradition serves as a delightful way to celebrate a piece of Chicago’s history.
