the city – the establishment of Fort Dearborn in 1803, the Chicago Fire in 1871, the World's Columbian Exposition in 1893, and the Century of Progress Exposition in 1933. The stripes represent the North and South branches of the Chicago River. The flag is very popular in the city, both for its bold design and as a sign of civic pride. Less well-known is the Chicago municipal device, a symbol that looks like the letter Y inside a circle. According to the Municipal Code of Chicago, the device is "for use by the varied unofficial interests of the city and its people". Its design is inspired by the confluence of the North, South, and main branches of the Chicago River at Wolf Point. The municipal device can be seen in various places around the city – for example on the marquee of the Chicago Theatre.
