Open House Chicago
Time Out says
Want to take a look inside skyscrapers, private clubs, churches, theaters and historic homes throughout the city? The Chicago Architecture Center annual Open House Chicago event offers a behind-the-scenes look at more than 350 buildings spread across 38 neighborhoods—and it's all absolutely free. This year's lineup of sites (the complete list is posted on the Open House website) adds locations in Irving Park, Portage Park and Jefferson Park, such as the Copernicus Center, Carl Schurz High School and the Irish American Heritage Center. In honor of the Year of Chicago Theater, you'll also be able to step into performance spaces such as the James M. Nederlander Theatre, the Second City and University of Chicago's new Green Line Performing Arts Center. All tours are first-come, first-served, so plot out your list and prepare to explore Chicago all weekend long.
