17 things about Chicago that sound made up but are completely real
I keep finding stuff about this city that makes me go "wait, that can't be right" and then it turns out it is.
- The Chicago River used to flow into Lake Michigan. In 1900 engineers reversed it so the city's sewage would flow toward the Mississippi instead. It's still flowing backwards today, more than 125 years later. St. Louis sued us over it and lost.
- The city raised itself out of the mud in the 1850s. Entire downtown blocks of brick buildings, including the Tremont House hotel with guests still inside, were lifted up to six feet using thousands of jackscrews turned by hand. A 22 year old George Pullman ran one of the crews.
- The skyscraper was invented here. The Home Insurance Building at LaSalle and Adams in 1885, ten stories, first building in the world held up by a steel skeleton instead of its walls. It got torn down in 1931.
- Twinkies, brownies, the cafeteria, the zipper, spray paint, roller skates, the remote control, pinball, softball, and the Ferris wheel were all invented in Chicago.
- The original Ferris wheel from the 1893 World's Fair was 264 feet tall, carried 2,160 people at once in 36 train-car-sized cars, and was built specifically to one-up the Eiffel Tower from the previous World's Fair in Paris.
- The 1893 World's Fair drew 27 million visitors at a time when the entire US population was 63 million. Almost half the country went.
- Walt Disney was born in Chicago. Hugh Hefner founded Playboy here. Both men's childhood homes are still standing on the West Side and Northwest Side respectively.
- The four stars on the Chicago flag represent Fort Dearborn, the Great Fire of 1871, the 1893 World's Fair, and the 1933 Century of Progress fair. There's an active citizen movement to add a fifth.
- Pope Leo XIV, elected in 2025, is from Dolton. He's the first American pope in history and he's a White Sox fan. The Vatican confirmed it.
- The 1979 Disco Demolition Night at Comiskey Park, where a DJ blew up a crate of disco records between games of a White Sox doubleheader, ended in a riot, a forfeit, and is widely cited as the cultural moment that killed disco.
- The "L" is older than the New York subway. The first elevated line opened in 1892. The Loop got its name from the elevated tracks that loop around downtown, not the other way around.
- Lower Wacker Drive exists because Daniel Burnham proposed in 1909 that the city should have multiple street levels stacked on top of each other. Most of the plan was never built, but the part downtown is why Billy Goat Tavern is underground and why the Batman movies film car chases here.
- There is a 6 mile pedestrian tunnel system, the Chicago Pedway, that connects 50 downtown buildings underground. Most Chicagoans have never used it. You can walk from the Thompson Center to Macy's to Millennium Station without going outside.
- The Sears Tower had a hidden 14th floor for decades that wasn't on any public elevator. It housed broadcast equipment for the antennae.
- Chicago has more Polish residents than any city outside Warsaw. It also has the second largest Mexican American population in the country after Los Angeles.
- The first ever blood bank was opened at Cook County Hospital in 1937 by Dr. Bernard Fantus, who coined the term.
- The Picasso sculpture in Daley Plaza, the giant rust-colored thing everyone sits on, has no official name. Picasso refused to give it one and refused $100,000 in payment. He donated it to the city.
Which ones did you not know? Got any I should add to the list?
