For the chapel constructed by Leo X at the fortress of Castel Sant'Angelo, Raffaello created a "Madonna". In addition, he sculpted a marble statue of Saint Michael holding his sword, designed to stand atop the Castel. (Legend holds that in 590 the Archangel appeared atop what was then the mausoleum of Hadrian, sheathing his sword as a sign of the end of the Roman plague, thus lending the fortress its present name). Raffaello's St. Michael was later replaced by a bronze statue of the same subject, executed by Flemish sculptor Peter Anton von Verschaffelt in 1753. His version may still be seen in an open court in the interior of the fortress.
