Take a tour of Orchestra Hall on its 100th Anniversary! Along the tour, learn about the building’s history, take in the magic of Orchestra Hall’s acoustics, and stand directly on stage where the greatest artists from the last century have performed. The tour is FREE (so is parking) and space is limited. Groups of 25 will leave every 30 minutes beginning at 2:00 PM, and the final tour takes off at 4:30 PM.
