The famous Passetto di Castel Sant’Angelo 🤩
An elevated and fortified corridor, about 800 meters long, connecting the Vatican (Apostolic Palace/Vatican City) with Castel Sant’Angelo!
Its construction dates back to the 13th century, and it is closely linked to the Città Leonina, the first true fortification built to protect the Vatican. Pope Leo IV (hence the name) had it erected in the 9th century to defend St. Peter’s and the surrounding area from Saracen raids.
The Passetto di Borgo was later added as a sort of “strategic extension.” It was not originally part of the Leonine Walls but took advantage of their defensive system by connecting to them.
It served as a safe escape route for the popes: in case of attacks or sieges, they could flee from the Vatican and take refuge in Castel Sant’Angelo, which was practically an impregnable fortress. Some popes also used it as a secret passage to meet lovers or “inconvenient” figures, far from prying eyes.
In my opinion, the last stretch, right next to Castel Sant’Angelo, is the most fascinating.
Have you ever visited it? Have you ever tried to spot it from the outside?
Best wishes and see you soon 🙂
