The newest addition to Calvary United Methodist Church is ensconced in the bell tower. A set of eight full circle peal bells cast by John Taylor Bellfounder of Leicestershire, England was installed in 2004. Calvary’s peal bells are a part of Frederick’s unique standing as possibly the only place in the world where all three Western bell instruments are within hearing distance of each other, along with the Carillon at Baker Park and the Chime Set at Trinity Chapel. In 2006, in commemoration of the 20th anniversary of the Tour of Historic Houses of Worship, all three sets of bells were rung at once.
In addition to Calvary's peal bell ringers, ringers from around the area occasionally gather at Calvary for peal attempts. For more information, contact .
