CHICAGO -- Chicago will be celebrating its 175th birthday today.



Sunday marks the day the city was incorporated -- March 4, 1837 -- and there will be events across the city to mark the occasion.



The Chicago History Museum, 1601 N. Clark St. the North Side will host a day of activities, including meet-and-greet sessions with actors playing historical luminaries such as Jane Addams. The cafe in the museum lobby will be selling hot dogs for $1.75 and there will be a commemorative cake made by Chicago's Bleeding Heart Bakery. Admission is free; the museum is open from noon to 5 p.m.



On the South Side, the DuSable Museum of African American history, 740 E. 65th Place, will feature interaction with historical characters and musical performances while celebrating DuSable Day. Jean Baptiste Pointe DuSable, a Haitian-born immigrant, was Chicago's original settler. Recognized as "the father of Chicago," he built his first home in the late 1770s on what is now the site of the Pioneer Plaza outside the Equitable building.



The museum is open noon-5 p.m. today; admission is free. There's also a special Sunday night concert from 7 to 9 p.m. featuring a musical tribute to DuSable led by composer Douglas Ewart; admission is $5 for DuSable members and $10 general admission.



Here's another option: Visit the city's oldest surviving building, Clarke House, at 1827 S. Indiana Avenue. It was built in 1836.
