Joliet | USA Illinois

Historical Timeline

Joliet was founded in 1833 and incorporated as a city in 1852. Primary governance eras include the initial canal-building period (I&M Canal), the "City of Steel and Stone" industrial boom (late 19th century), and the late-20th-century transition toward a gaming and entertainment-based economy. The city's urban form was primarily defined by its limestone quarries and its location as a critical node on the Des Plaines River and the Rock Island Railroad. The 1990s introduction of riverboat casinos is the primary event that shaped its modern economic landscape.

Facts & Legends

Joliet is home to the Old Joliet Prison, which served as the filming location for the opening scenes of the 1980 film The Blues Brothers. Historically, the city was the only place in the world that produced "Joliet Limestone," a distinct dolomite used to build the Illinois State Capitol and the Chicago Water Tower. A local legend involves "Mount Joliet," a large earthen mound once located southwest of the city that early explorers believed was a man-made pyramid built by indigenous peoples; it was eventually mined away for its clay and gravel.
