Lemont High School’s Performing Arts Center not only serves the school's students and staff, but also the Lemont community. The Performing Arts Center is available for use as an auditorium, a teaching facility, and a place for educational, cultural and civic events.

The 847-seat facility opened in March 2008.

Lemont High School and its associated programs have first priority, whether students are the performers or the audience. The next priority for use includes all other public schools in Lemont. In addition, the facility is available to organizations, municipal groups or individuals within the district who wish to sponsor appropriate civil, cultural, educational, recreational or political activities, as long as these activities do not interfere with the conduct of the school’s programs and are in the best interest of the school system.
