Bells

The Basilica has 6 bells, placed in the room under the Roman clock, only 3 of them are visible from ground level while the rest are hidden behind the bourdon. They range from the smallest which is 260 kg to the massive bourdon that approximately weighs 9 tonnes. From 1931, the bells are operated electrically, thus permitting even the largest bell to be tolled from a distance. The oldest bell Rota dates from 1288 and the bourdon called Campanone is rung at Christmas and Easter, on the Solemnity of Sts. Peter and Paul, and every time the Pope imparts the " Urbi et Orbi " blessing to the city and to the world. Campanone also announces the death of the pope and an election of a new pope.
