Visit the web site and listen to the bells! The carillon is played on weekdays at noon. The public may visit the tenth floor observation deck during and after the recitals to view the carillon. The Charles Baird Carillon, fourth heaviest in the world, contains 53 bells. The largest bell, which strikes the hour, weighs 12 tons while the smallest bell weighs 16.5 pounds. The bells are stationary, hung on a steel framework in the bell chamber 120 feet above the campus.
