The award-winning St. Helena High School Auditorium was a project to replace the existing auditorium at its existing location. The new auditorium consists of a 350-seat audience chamber and a 2,200 square foot stage. The auditorium building also has a large entry lobby, a drama classroom with changing areas, large storage rooms, and a band room as an alternate. The main entrance to the auditorium faces toward the existing Redwood Grove and consists of new paving routes to the existing library and vintage hall.
