Chicago is located in the Midwest along the Great Lakes shoreline. It is the third largest city and metropolitan area in the United States with a city population approaching 3 million and a metro population approaching 10 million. Chicago is a huge vibrant city and metropolitan area that sprawls over 10,874km². It's well known for house music and electronic dance music, blues, jazz, comedy, shopping, dining, sports, architecture, highly-regarded colleges and universities, and premier cultural attractions.
Chicago was known as a fine place to find a wild onion if you were a member of the Potawatomi tribe, who lived in this area of Illinois before European settlers arrived. It was mostly swamps, prairie and mud long past the establishment of Fort Dearborn in 1803 and incorporation as a town in 1833. The city later undertook civil engineering projects of unprecedented scale to establish working sewers, even reversing the flow of the Chicago river to keep unclean water out of the city's drinking supply, and stop buildings from sinking back into the swamps — and that was just the first few decades. By 1871, the reckless growth of the city was a sight to behold, full of noise, Gothic lunacy, and bustling commerce. But on October 8th, Mrs. Catherine "Cate" O'Leary's cow reportedly knocked over a lantern in the crowded immigrant quarters in the West Side, and the Great Chicago Fire began. It quickly spread through the dry prairie, killing 300 and destroying virtually the entire city. The stone Water Tower in the Near North area is the most famous surviving structure. But the city seized this destruction as an opportunity to rebuild bigger than before, even inventing the skyscraper in Chicago; which of course, would be picked up and utilized in cities worldwide in the modern day. In addition, several architects and urban planners of Chicago would go on to become legends of modern architecture.
