As the Chicago Architecture Biennial comes to an end, the Chicago Cultural Center must close for a few days to deinstall the Biennial exhibits. The Cultural Center will be closed on Monday, January 6 and Tuesday, January 7. If you are giving a Historic Treasures tour on either of these dates, please keep in mind that you will not be able to enter the Cultural Center. The Tiffany Treasures tour for January 7 has been cancelled.
