Castel Sant’Angelo history explained
Mausoleum of Hadrian
135 - 139 AD
The Castel Sant'Angelo, originally known as the Mausoleum of Hadrian, was built between 123 and 139 AD under the direction of the architect Decrianus. It was designed as a mausoleum for Emperor Hadrian and his family, inspired by the Mausoleum of Augustus. The original mausoleum consisted of a square base and a cylindrical building, with a tower containing three burial chambers. After Hadrian's death, the mausoleum became the final resting place for several emperors and their families.

Transformation into a fortress
500 - 590 AD
Due to the shifting political and security needs of Rome during a tumultuous period of decline and invasions, the mausoleum was converted into a military fortress. Emperor Honorius played a pivotal role in incorporating the building into Aurelian Walls, strengthening Rome's defenses. This fortified structure, later known as Castellum Crescentii in the Middle Ages, successfully protected the Vatican from the Vandals of Genseric's plundering in 455 AD. In the early 6th century, Theodoric repurposed the building, turning it into a state prison.
Papal residence and prison
590 - 1527 AD
In 590 AD, during a plague, Pope Gregory I had a vision of the archangel Michael sheathing his sword over the castle, symbolizing the plague's end. This vision led to the castle being named Castel Sant'Angelo. Throughout the Middle Ages, it served as a sanctuary for popes, reachable from the Lateran through a secure passage. Popes transformed it into a residence and refuge, fortifying it against external threats. It was also used as a prison for political prisoners. The most famous prisoner was the Italian adventurer Benvenuto Cellini.
Renaissance and Baroque additions
1492 - 1789
In the 16th century, under Pope Paul III, the castle underwent significant renovations. Antonio da Sangallo the Younger added a cylindrical bastion, and later architects including Michelangelo, Giacomo Della Porta, and Bernini made additional modifications, such as the Passetto di Borgo, a secret passage connecting the Vatican to the castle.
Modern use & Museum
1789 - present
After the unification of Italy in the 19th century, the castle was used as a barracks and military prison. In 1901, it was officially designated as a national monument and turned into a museum, showcasing its rich history and displaying various artworks and artifacts. Today, visitors can explore its battlements, and underground passages, and enjoy panoramic views of Rome from the terrace.
