ne of CSU, Chico’s three oldest buildings is Trinity Hall, a fine example of Romanesque Revival in the Mediterranean style of Lombardy. Built in 1931, its square bell tower resembles campaniles found in Italy. The chimes from the tower are still heard throughout central Chico on the hour and half hour. Initially the campus library, Trinity Hall later became the Campus Activity Center and today is a department and faculty office building. It is also home to the new Humanities Center, a program dedicated to intellectual exchange and discussion between faculty and students in the Humanities and Fine Arts.
