When the church was constructed in 1787, there was only a weather vane on the roof. In 1830, a cupola was built, and a bell cast in 1816 in Belgium and weighing 300 pounds was installed. This bell was removed in 1891, sent first to Frederick, MD, then in 1907 was installed at St. Andrew on the Hudson Jesuit Novitiate, Hyde Park, NY, now The Culinary Institute of America. On June 21, 1891, a 2000 pound bell in honor of St. Aloysius Gonzaga was blessed and installed. Over the years a crack developed, which altered the sound, and it was removed on March 14, 1984. On that same day, the present "Bicentennial" bell, the same size, was installed after it was blessed by Bishop William H. Keeler on March 11, 1984, and named St. George in honor of Bishop George L. Leech.
