Chicago is the capital of the U.S. state of Illinois and the third-most populous city in the United States after New York City and Los Angeles. The city is situated on the shores of Lake Michigan, one of the 5 Great Lakes of North America.
This means that a lot has happened since the first non-Indigenous man named Jean Baptiste Point du Sable, referred to as the “Founder of Chicago,” settled in the area in the 1780s.
The town wasn’t established until 1833 and the city of Chicago was incorporated on March 4, 1837, with a population of fewer than 6,000 inhabitants.
As the city became an important transportation hub that interconnected the Great Lakes named the “Chicago Portage,” the city grew exponentially.
It was the fastest-growing city in the world for many decades in the 19th century and countless construction projects turned this small town into a bustling metropolis.
Let’s take a closer look at some of the most famous buildings in Chicago, architecture that you must check out when you’re in the city!
