The Mausoleum of Emperor Hadrian, usually known as Castel Sant’Angelo (Castle of the Holy Angel), has a grand view and impressive history. During its long existence, built at the dawn of Christianity on the banks of the Tiber, the cylindrical mausoleum was the last refuge for the Roman emperor, the residence of pontificals, a fortress, then prison, and later – the museum and treasury.

Things to Know Before Visit the Castel San Angelo

Why is Castel Sant Angelo important?

Castel Sant'Angelo holds crucial significance due to its multifaceted history. It was a mausoleum, a fortress, a Papal residence, a prison, and now a museum. Moreover, it houses important Renaissance artworks, and its strategic location near the Vatican made it pivotal in religious and political affairs.

Is Castel Sant’Angelo worth a visit?

Absolutely, Castel Sant'Angelo is worth a visit. It's not only a significant historical site with varied roles over centuries but also a rich museum hosting Renaissance artworks. Its rooftop offers some of the most panoramic views of Rome.

Who built Castel Sant’Angelo, and when was it constructed?

Castel Sant'Angelo was commissioned by Roman Emperor Hadrian as a mausoleum for his family. Construction began in 134 AD and was completed in 139 AD. The architect was Demetriano.

What was the original purpose of Castel Sant’Angelo?

The original purpose of Castel Sant'Angelo was to serve as a mausoleum for Emperor Hadrian and his family. It was a part of Hadrian's efforts to memorialize and immortalize his family line within the architecture of Rome.

Is Hadrian still buried at Castel Sant Angelo?

No, Emperor Hadrian is no longer buried at Castel Sant'Angelo. While initially a mausoleum for Hadrian and subsequent Roman emperors, it's believed that the original remains were lost over time, especially during the sieges and spoliations.

How did Castel Sant’Angelo transition from a mausoleum to a fortress and then to a museum?

The transition of Castel Sant'Angelo occurred over centuries. Originally a mausoleum for Emperor Hadrian and his family in 139 AD, it was fortified and integrated into Rome's city walls by 403 AD. In the 14th century, the popes converted it into a castle. Since 1901, it serves as a public museum.

Can visitors tour the inside of Castel Sant’Angelo?

Yes, visitors can tour the inside of Castel Sant'Angelo. The interior includes historical artifacts, Renaissance-era paintings, and decorated rooms from when it was a papal residence. Moreover, visitors can enjoy panoramic views of Rome from the terrace.

What is the significance of the statue of the archangel Michael on top of Castel Sant’Angelo?

The statue of Archangel Michael is symbolic of the biblical legend where the angel appeared above the castle in 590 AD, sheathing his sword, marking the end of a plague, hence giving the castle its present name, Castel Sant'Angelo or Castle of the Holy Angel.

Are there any notable artifacts or exhibits inside Castel Sant’Angelo?

Yes, Castel Sant'Angelo houses a rich collection of artifacts and exhibits. These include Renaissance paintings, military memorabilia, antique weaponry, and papal apartments decorated by leading 16th-century artists like Perino del Vaga and Giovanni da Udine.

What is the connection between Castel Sant’Angelo and Vatican City?

Castel Sant'Angelo and Vatican City are connected by the fortified corridor known as Passetto di Borgo. In times of danger, this passageway was used by popes to move between Vatican City and the secure fortress of Castel Sant'Angelo.

Is Castel Sant’Angelo part of Vatican City?

No, Castel Sant'Angelo is not a part of Vatican City. It is located in the city of Rome, Italy. However, historically, it was connected to the Vatican through a fortified corridor for use during periods of danger.

How can I get to Castel Sant’Angelo from the center of Rome?

From the center of Rome, the quickest way to reach Castel Sant'Angelo is by bus. Route 64 from Termini station and Route 40 from Piazza Venezia both stop at Piazza Pia, just a short walk from the castle. Alternatively, it's a 10-minute walk from St. Peter's Square.

What are the operating hours and admission fees for Castel Sant’Angelo?

Castel Sant'Angelo is open Tuesday to Sunday from 9:00 AM to 7:30 PM. The full ticket price is 15 Euros.

The History of the Castle’s Construction

The Mausoleum of Hadrian

The tomb of Emperor Hadrian Publius was erected on the high bank of the river in about 139 AD. The original mausoleum had the form of a cylinder and was richly decorated. The flat roof of the building featured an ornamental garden in the center of which a gilded quadriga was set. In 138, the Emperor’s ashes were placed in the tomb with his wife Sabine and adopted son urns. Also, on Hadrian’s order, Ponte Sant’Angelo (Bridge of Hadrian) was built from the center of Rome to the tomb.

Decline

By the 5th century AD, Hadrian’s mausoleum had lost its former luster and solemnity. It was gradually transformed into a military fortress. During the Goths’ invasion, most of the bronze ornaments, urns, and statues were stolen or destroyed.

There is a legend which says that the Archangel Michael appeared above the mausoleum putting his sword back into the sheath. Thus, the end of the plague in 590 AD was marked. To celebrate this, the tomb was given its present name.

Another interesting fact: in Italy and in many other European countries, a man who had just sneezed said: “God bless you!“. In the Middle Ages, it was believed that the plague began with sneezing attacks. And only God could help the plague ill person!

By the 14th century, Castel Sant’Angelo in Rome became the pope’s residence. Nicolaus III connected the castle to St. Peter’s Basilica (Italian: Basilica Papale di San Pietro in Vaticano) by a covered corridor called Passetto di Borgo. Pope Clement VII found refuge in the castle during the invasion of Charles V’s army in 1527 in Rome. The inhabitants of the besieged fort actively attacked the enemies through the slit windows. Famous sculptor-goldsmith Benvenuto Cellini was one of those glorious defenders.

A little later, comfortable apartments ordered by the pontificate appeared on the mausoleum territory if the story of the siege would repeat. Unfortunately, the castle also served as a prison for some time.

  • For example, famous medieval scientist, astrologer, and Dominican monk Giordano Bruno had been confined within the walls of Castel Sant’Angelo for 6 years!
  • It is remarkable that later one of the defenders of the fort, Benvenuto Cellini, fell into disgrace of the pontificate and went to prison too. On the other hand, nimble and skillful sculptor Cellini even managed to escape from the castle.
  • Since 1901, Castel Sant’Angelo has been officially declared a national museum (Museo Nazionale di Castel Sant’Angelo).

Architecture

The main architectural ensemble of Castel Sant’Angelo was formed long ago, during the reign of Emperor Hadrian. A powerful cubic foundation was faced with expensive marble. There was a “washer” of the mausoleum on the top of the pedestal, made of volcanic stone. Outside, the building was faced with travertine and decorated with carved pilasters in the form of oxen’s heads (Bucrani). The tomb was surrounded by a wall that served as a decoration as well as a fortification.

Nowadays, the castle looks much more modest than it was under Hadrian. Travertine, marble, pilasters, and bronze were lost over the centuries. However, the external structure of the mausoleum has remained almost unchanged in contrast to the internal one. Ancient tombs where the Emperor and his family, Antonius Pius, Marcus Antonius, and their nobles rested were damaged. Urns with the ashes were lost.

In the 14th century, the mausoleum has been turned into a fortress. Pope Boniface IX (Latin: Bonifacio IX) ordered the architect, Niccolo Lamberti, to strengthen the castle walls, equip bastions and create the only entry in the form of a drawbridge. In the building itself, a new premise – St. Michael’s Chapel (Italian: Cappella San Michele Arcangelo) – appeared.

In the 15th century, Pope Alessandro VI of the house of Borgia said that architect Antonio Giamberti da Sangallo had to turn the castle into a natural stronghold for battle. The castle was fortified with four bastions and a ditch around the buildings. The fortress also had papal apartments which featured frescoes from the famous Pinturicchio. The new palace of Alessandro VI was used for luxurious receptions and celebrations.

In 1536, Raffaello da Montelupo created a statue of the Archangel Michael with a sword. The marble saint with bronze wings reminds the Romans of the events described in the legend and protects the castle. In the 17th century, in the castle, Angel’s Patio appeared where de Montelupo’s Archangel had found its place.

In the second half of the 17th century, Urbano VIII destroyed most military and decorative buildings of the 15th and 16th centuries. Instead, he created a new version of the fort with a solid defensive wall and fortifications. They began to decorate Ponte Sant’Angelo, leading to the castle, with the statues of angels in 1667. Giovanni Lorenzo Bernini and his students have spent about two years completing 10 Baroque-style sculptures that guard the bridge today.

In the 18th century, Archangel Michael saw the world not in stone but in bronze. The work of Flemish sculptor Peter Anton von Verschaffelt still adorns the castle’s roof.

Interesting Facts about Castel San Angelo

  1. Castel Sant’Angelo was initially built as a mausoleum for Emperor Hadrian and his family. Construction began in 134 AD under architect Demetriano and was completed in 139 AD. The circular design was unique for a mausoleum, reflecting Hadrian’s refined taste.
  2. In 401 AD, the building was repurposed as a military fortress and incorporated into Aurelian Walls. As Rome’s political and military dynamics changed, so did Castel Sant’Angelo, transforming from a tomb to a crucial defensive structure in just over two centuries.
  3. One of the castle’s most distinctive features is the bronze statue of Archangel Michael at the top. The statue commemorates the vision of Pope Gregory the Great during the plague of 590 AD, where he saw the angel sheathe his sword, signaling the end of the epidemic.
  4. The fortified passageway, Passetto di Borgo, links Castel Sant’Angelo to Vatican City. The 800-meter-long corridor served as a secure escape route for popes in times of danger, most notably by Pope Clement VII during the Sack of Rome in 1527.
  5. Inside Castel Sant’Angelo, there are intricate frescoes by 16th-century artists Perino del Vaga and Giovanni da Udine. These artists were part of Raphael’s workshop, and their artwork is displayed in the intricate decorations of Pope Paul III’s apartment.
  6. Since 1901, Castel Sant’Angelo has functioned as a museum. It’s home to a vast collection of historical artifacts, including Renaissance paintings, military weaponry, and documents, providing a deep insight into Rome’s rich and diverse history.
  7. The castle offers one of the most panoramic views of Rome, a vista that hasn’t changed much since the 16th century. Visitors can see the Tiber River, Vatican City, and a significant portion of the historical city center from its terrace.
