Castel Sant'Angelo is a massive cylindrical fortress on the bank of the Tiber in Rome. It was built as a mausoleum for the emperor Hadrian and his successors, and was completed in the second century. In late antiquity it was turned into a fortress, and in the Middle Ages the popes took it over and linked it to the Vatican by a fortified passage, the Passetto di Borgo, along which Pope Clement VII escaped during the Sack of Rome in 1527. Its name comes from a legend that Pope Gregory the Great saw an angel sheathing a sword above it, ending a plague. It later served as a prison and barracks, and is now a museum.
