The heart of the theater, including its 1,525-seat auditorium, is built underground. A lower lobby gives patrons direct access to the adjoining underground Millennium Park Garage. The Theater extends Chicago's vibrant performing arts district east to Lake Michigan, and links it with the museum campus and many other cultural institutions along Michigan Avenue. While located in Millennium Park, the theater is privately funded through contributions and grants from individuals, foundations and corporations. It is built on land leased from the City of Chicago.
