Rockefeller Chapel is the spiritual and ceremonial center of the University of Chicago, and a major performing arts producer, offering music, theatre, and visual arts events to citywide audiences. A leading venue for the choral arts, it is a prized event location for major speakers and international artists. It is the home of two world class instruments, the carillon and organ. Resembling a medieval cathedral in appearance and size, it hosts festivals and ceremonies of many world religious traditions, as well as Sunday services where the soaring architecture is matched with the poetry and theatre of grand liturgy of diverse origins, and with the beautiful voices of its choristers.
