Castel Sant'Angelo - Papal Fortress, Residence and Prison

Papal Fortress, Residence and Prison

The popes converted the structure into a castle, beginning in the 14th century; Pope Nicholas III connected the castle to St. Peter's Basilica by a covered fortified corridor called the Passetto di Borgo. The fortress was the refuge of Pope Clement VII from the siege of Charles V's Landsknechte during the Sack of Rome (1527), in which Benvenuto Cellini describes strolling the ramparts and shooting enemy soldiers.

Leo X built a chapel with a Madonna by Raffaello da Montelupo. In 1536 Montelupo also created a marble statue of Saint Michael holding his sword after the 590 plague (as described above) to surmount the Castel. Later Paul III built a rich apartment, to ensure that in any future siege the Pope had an appropriate place to stay.

Montelupo's statue was replaced by a bronze statue of the same subject, executed by the Flemish sculptor Peter Anton von Verschaffelt, in 1753. Verschaffelt's is still in place, though Montelupo's can be seen in an open court in the interior of the Castle.

The Papal state also used Sant'Angelo as a prison; Giordano Bruno, for example, was imprisoned there for six years. another prisoner was the goldsmith Benvenuto Cellini. Executions were made in the small interior square. As a prison, it was also the setting for the third act of Giacomo Puccini's Tosca from whose ramparts the eponymous heroine of the opera leaps to her death.
