The tower is 38 feet square at the base and 210 feet high. It is the only element of the Chapel that imitates a detail of another building: it is modeled on the Bell Harry Tower of Canterbury Cathedral. But, instead of being located over the crossing of the nave and the transept—as is traditional for English Gothic cathedrals—the Chapel tower is situated above the narthex.

100 feet above the Chapel entrance is the Tower Historical Room. Built into the walls of this room are cornerstones from the original Trinity College campus in Randolph County, North Carolina, and from former East Campus buildings. The Historical Room provides access to the space between the ceiling and the roof of the nave. Visible at this level is the steel skeleton that supports the roof of the Chapel. Also visible are the winches used to lower the chandeliers to pew level for cleaning and general maintenance. 

The next room in the tower is the carillon studio, which houses the keyboard used to play the carillon. From this level, doors open onto balconies on each of the tower’s four sides. Above the carillon studio is the large, open chamber where the bells hang. An adjacent stairwell leads to the roof  and elevated observation deck.
