Did you know that the Chicago River didn’t always flow into the Mississippi? It once emptied into Lake Michigan, but in 1900, the flow was reversed in order to make the drinking water safe. By digging a canal, huge feat of engineering, over eight long grueling years, this reversal helped rid the city of serious disease outbreaks.

There are over 10,000 bodies in Lincoln Park. This spot once was the City Cemetery, and while many of the bodies were removed, The Great Chicago Fire destroyed a lot of the gravemarkers and many were left behind. (As a side note, a much bigger fire took place in Washington the same day as the Great Chicago Fire.)

There is a massive network of tunnels right beneath your feet! Now abandoned and sealed with water, these tunnels 40 feet below were used to transport coal. While they may not be used for that purpose anymore, they play a major part in flood control and water filtration in the Windy City.
