The mighty bell Maria Dolens, one of the largest outside Russia and East Asia, and the second-largest swinging bell in the world after the St. Peter's Bell of the Cologne Cathedral. Maria Dolens ("the grieving Virgin Mary") was built under the inspiration of a local priest, between 1918 and 1925, to commemorate the fallen in all wars, and to this day it sounds for the dead every day.
