The Windy City goes green.
Landmarks all over the world will turn green over the next few days to celebrate St Patrick's Day.
We'll all celebrate on March 17 but parades are already taking place across the globe and Chicago held their one on Saturday.
To mark the event, the Chicago River, which flows through the middle of the city, went bright green for the day.
