The Castel Sant'Angelo, initially known as the Mausoleum of Hadrian, is a fortress located in Rome, reachable via the Ponte Sant'Angelo. It is an end point to the Passetto di Borgo, and is found on the banks of the Tiber river.

The castle was commissioned by the Roman Emperor Hadrian as a tomb for himself and his family. Later, during the Renaissance, the building was used by the Papacy as a fortress, a castle and a prison.


Roman era[]

The tomb of Hadrian, also called Hadrian's mole, was constructed between 135 and 139. It was originally a decorated cylinder, with a garden top and golden quadriga.[1]

Hadrian's ashes were placed here a year after his death in 138, together with those of his wife, and his first adopted son, who died in the same year. Furthermore, remains of succeeding emperors were placed here as well. Hadrian also built the Ponte Sant'Angelo, formerly known as Pons Aelius.[1]


Much of the tomb contents and decoration had been destroyed since the building was changed into a military fortress in 401. The urns and ashes were scattered by looters in Alaric's sacking of Rome in 410, and the original decorations were thrown down upon the attacking Goths when they besieged Rome in 537.[1]

Liberation of Rome[]

In 1499, the Assassin Ezio Auditore da Firenze scaled the castle during his infiltration of the Cappella Sistina, in order to assassinate Pope Alexander VI.[2]

In 1501, upon Ezio's return to Rome, he infiltrated the Castel Sant'Angelo to rescue Caterina Sforza, and to assassinate Cesare and Rodrigo Borgia. However, though he successfully rescued Caterina, he was unable to kill either of the Templars, after he discovered that Rodrigo was away from the castle, and that Cesare had left for Urbino moments after Ezio had arrived.[3]

Soon after this assault, the castle was guarded by several Papal Guards and French soldiers, courtesy of Cesare's alliance with the French General Octavian de Valois.[3]

In August 1503, Ezio once again infiltrated the Castel Sant'Angelo through a side gate, with a key he had obtained from Lucrezia Borgia's lover, Pietro Rossi. At a window looking into the castle's Papal apartments, he witnessed the murder of Rodrigo at the hands of Cesare. At this time, Ezio also found out the location of the Apple of Eden from Lucrezia.[3]

Around 1506, working with the Italian Assassins, Sirus Favero tasked Lo Sparviero, the assassin sent by Niccolò Machiavelli, to intercept one of the Crow messengers and took a very important letter from him. The messenger sooner appear on the Ponte Sant'Angelo.[4] Lo Sparviero identify the messenger and killed him to retrieve the letter. Lo Sparviero handed the letter to Favero in the Castel Sant'Angelo and saw his suspicious behavior. He followed him through the Ponte Sant'Angelo. Sooner he found out that Favero was the leader of the Crows, the man called "Il Corvo".[4][5]

After a few weeks, Machiavelli learned the message, Favero was summoning all his Crows ready to attack the Brotherhood in Roma.[6] He signaled Lo Sparviero to help him to take down Il Corvo. The leader was opposite the Ponte Sant'Angelo. Lo Sparviero managed to cross under the bridge and avoid the most of the crows on the bridge. He eventually killed Il Corvo and his bodyguards.[7] Leading to the surrender of most of the Crows, and return to meet Machiavelli.[6]

Modern times[]

In 2016, the Castel Sant'Angelo was used to as a simulated location by Abstergo Entertainment for their Identity Project. Like most of the simulated locations in the Project, the Castel had two aesthetic variations, and as such, could be utilized during sunset and daybreak.[8]


  • After climbing the flagpole and looking out at the cityscape, clouds appeared below the pole itself.
  • One of Clay Kaczmarek's rifts was located on the castle, on the main tower just across from the inner wall.
  • The entire castle was a restricted area throughout Assassin's Creed: Brotherhood, except during certain memories, such as "The Ezio Auditore Affair."
  • The achievement "Fly Like An Eagle" could be earned once Ezio jumped from the pinnacle of the castle with a parachute.
