The new Robert W. Plaster Free Enterprise Auditorium will seat 700, with 500 seats in the main space and 200 in the balcony. It’s double the size of any other auditorium on campus. All CCA (Center for Constructive Alternatives) lectures will be given in the auditorium. CCAs are known to be some of the most successful initiatives on Hillsdale College's campus where students, faculty, staff, and friends of the College come together for learning.
