 The largest is the "Salvator Bell" with a diameter of 2.3 m and weighing in at 10 tons.Of the old bells only the "Lobdeburg Bell", by Cunradus Citewar of Würzburg, the most prominent bellfounder of his time, dates from 1257.Because it was taken down in 1933 and stored in the crypt, it is the only ancient bell of the cathedral to have survived the firestorm caused by the bombing of 16 March 1945.
