For the 10th year, the Chicago Fed is opening its doors for the Chicago Architecture Center’s signature (and free!) festival, Open House Chicago. On Saturday, October 17, and Sunday, October 18, visitors will have exclusive access to the Great Hall in the 104-year-old Federal Reserve Bank of Chicago building and to its Money Museum.

The Chicago Fed is one of more than 200 architecturally, culturally, and historically significant sites participating in Open House Chicago. This free, annual festival is one of the largest events of its kind in the world, showcasing locations across the city—many of them typically inaccessible to the public.
