History
Fort Dearborn was built here in 1803, and the Town of Chicago, incorporated in 1833, covered almost the entire Loop. The Great Chicago Fire of 1871 destroyed most of downtown, and the rebuilding produced the Home Insurance Building (1885), often called the first skyscraper.
The name may date to an 1882 cable car circuit, though some researchers tie it to the elevated Union Loop built in 1895–97. Chicago’s address grid has started at State and Madison since 1909. Millennium Park opened in 2004.
