This summer, cool off in the Stewart Auditorium with a bag of popcorn in a place where you don’t have to worry if your kiddo cries in the middle of the movie. Your ticket gets you $1 off the Ruckus Rodeo exhibit too—don’t miss the hands-on, outdoor kids’ corral. Buy tickets ahead; these movies sell out! Learn more and buy tickets


Don't miss our free Summer Concert Series, held in our outdoor courtyard in June and July. The Auditorium acts as backup in case of rain for these concerts.
