Belfries are constructions which mainly serve for housing of a bell. They are used to announce occurrences, such as deaths, natural disasters, dangers and other things. They also serve as a timekeeping instrument for the closest surroundings. They were built mainly at easily accessible locations, from which the ringing of the bell could be heard in wide surroundings, or near the churches which did not have their own tower with a bell. It often times happened that a belfry by a church was later reconstructed to be incorporated in the church building, or conversely, that after demolishing of a church, only the tower remained to serve as a belfry. In the recent period, small belfries have started to appear to mark the places of former significant constructions or the places of reverence.
