Filming Of Transformers 3', Chicago, United States

Globally recognized, Chicago has numerous nicknames, which reflect the impressions and opinions about historical and contemporary Chicago. The best known include: "Chi-town", "Windy City", "Second City", and the "City of Big Shoulders". Chicago has also been called "the most American of big cities".
During the mid 18th century the area was inhabited by a native American tribe known as the Potawatomis, who had taken the place of the Miami and Sauk and Fox peoples. The first known non-indigenous permanent settler in Chicago, Jean Baptiste Pointe du Sable, who was a man of mixed African and European heritage born in Saint-Domingue (modern day Haiti), arrived in the 1770s, married a Potawatomi woman, and founded the area's first trading post. In 1795, following the Northwest Indian War, an area that was to be part of Chicago was turned over by some Native Americans in the Treaty of Greenville to the United States for a military post.
