You hear this all the time: Chicago is a city made up of neighborhoods. Go anywhere in the city and many times you’ll find signs of immigrant cultures that first settled those areas. But have you ever wondered why Bucktown is called Bucktown. Or River North. Or Bridgeport? Or Uptown? It’s pretty obvious why Ukrainian Village and Little Italy are called what they are, but why is Pill Hill on the South Side Pill Hill? (It’s because of all the doctors that lived in the area). Want to know how your neighborhood got named? Check out this extensive list from Mental Floss and prepare to say “huh” at least twice.
