During the Communist reign, the bell tower was used as an observation point for the secret police to spy on embassies of Western countries. The different equipment used in the espionage at the time is still in place at the bell tower. If you do choose to climb the 65 meters of the tower, you will not only have a magnificent panoramic view, but you will also be plunged into the dark history of the former regime.
