In some liturgical churches, bells are blessed before they are hung
In the Roman Catholic Church the name Baptism of Bells has been given to the ceremonial blessing of church bells, at least in France, since the eleventh century. It is derived from the washing of the bell with holy water by the bishop, before he anoints it with the oil of the infirm without and with chrism within; a fuming censer is placed under it and the bishop prays that these sacramentals of the Church may, at the sound of the bell, put the demons to flight, protect from storms, and call the faithful to prayer
