Passetto di Borgo

The Passetto di Borgo is a medieval elevated corridor constructed in 1277 that connects St. Peter's Basilica in Vatican City with Castel Sant'Angelo in Rome. It served as a protected and secret passage primarily used by popes to escape danger during times of threat. Architecturally, it is a notable example of Rome's defensive structures, embodying historical and strategic significance.

This passage has played a prominent role in papal history and is linked to several notable events involving papal escapes. Its secrecy and elevated structure allowed safe and discreet transit between the Vatican and the castle. The corridor has also been referenced in popular culture, including works like Dan Brown's novel Angels & Demons and the game Assassin's Creed II, highlighting its cultural as well as historical importance.

The Passetto di Borgo remains an architectural landmark within the Borgo district and can be recognized for its unique function as a hidden bridge. It provides insight into Rome's medieval defensive and papal security measures, reflecting the tense historical periods during which it was actively used.
