In the south corner of the church there is a tall, slim bell tower that has a square plan with a prism-shaped roof. The tower has seven floors (base floor plus six), where the base is the foundation of the entire structure. As we ascend through the bell tower, the structure becomes lighter in weight because of the larger windows near the top of the tower. On each of the plants there is the same amount of windows on the four sides of the tower, and there are five arcs in the space around the windows.
