When the bell tower was dedicated in 1931, it had a manual bell-ringing system, complete with handles to push (right) and bellropes. Today, all that remains of that system are 12 holes in each floor of the bell tower, where bellropes used to run, and the shown handle mechanism. Marks plays the bells on gamedays from a special keyboard connected to the current, mechanized bell system. On Oct. 1, 2021, she returns the keyboard to its storage space after playing a tune. That day, UNC hosted Duke in football. It was a Carolina win.
