Castel Sant’Angelo Tickets & Secret Passetto di Borgo Experience at Castel Sant'Angelo

Why visit Castel Sant'Angelo and the Passetto di Borgo?

Castel Sant'Angelo has been a mausoleum, military fortress, papal residence, and prison over nearly 2,000 years. Combined with exclusive access to the Passetto di Borgo, the elevated corridor popes used as a secret escape route to the Vatican, this ticket covers one of the most layered historic sites in Rome.

What is the Passetto di Borgo?

The Passetto di Borgo is an 800-metre fortified walkway running along the top of a medieval wall between Castel Sant'Angelo and Vatican City. Built in the 13th century and reinforced by Pope Alexander VI, it served as an emergency escape route. In 1527, Pope Clement VII used it to flee to the castle during the Sack of Rome by the troops of Charles V. Marks from arquebus fire are still visible on the walls. This narrow corridor, normally closed to the public, is accessible with this ticket either as a self-guided visit or with an optional guided tour.

What can I see inside Castel Sant'Angelo?

The castle's six levels are connected by the original 2nd-century helical ramp built for Hadrian's mausoleum. As you climb, the building transitions from ancient Roman tomb to Renaissance palace. Highlights include the papal apartments decorated by masters such as Perino del Vaga, the Treasury with its collection of arms and armour, the prison cells where political and religious prisoners were held, and the rooftop terrace crowned by the bronze Angel of the Castle, offering some of the best panoramic views in Rome.

How do I choose between self-guided and guided?

The self-guided option includes timed entry to the Passetto di Borgo and skip-the-line access to the castle, letting you explore both at your own pace. The guided tour option adds an English-speaking guide who brings the corridor's history to life with stories of papal escapes, sieges, and secret diplomacy. Both options include full castle access.
