Officially the Cattedrale di Santa Maria Assunta (Cathedral of Santa Maria Assunta), Naples’ most famous and beloved church is commonly known as simply the Duomo. The hub of Neapolitan spiritual life, the Naples Cathedral is also home to the annual miraculous liquefaction of the blood of patron saint, San Gennaro, one of the city’s cultural touchstones.

The Duomo di Napoli is the seat of the archdiocese and has a complex history that stretches back almost 1,000 years. It houses two additional religious buildings, which were incorporated into the design of the cathedral and now serve as two side chapels: the Basilica of Santa Restituta, with the ancient Baptistery of San Giovanni; and the Chapel of the Treasure of San Gennaro, where the relics of the beloved patron of the city are kept.

No walking tour of Naples is complete without a stop at its spectacular cathedral. Here’s all you need to know to get the most out of your visit.

A Brief History of the Duomo in Naples

The construction of the Cathedral began in the 13th century when the city was under Angevin rule, but several religious buildings had already occupied the site for centuries. The Basilica of Santa Restituta and another early Christian church - known as the Basilica Stefania and built on the ruins of a Roman temple probably dedicated to the god Apollo - both stood here when the construction of the new cathedral was commissioned by King Charles II of Anjou.

The king entrusted the design to French and Italian architects, including Giovanni and Nicola Pisano, and the cathedral was completed during the reign of his son Roberto in 1314.

Over the centuries, the Cathedral of Naples has survived collapses, bombings, earthquakes, and a series of renovations in various architectural styles. The interiors, the apse, and the facade have been modified or rebuilt several times, first in the gothic style, then in the baroque style, and finally in the current neo-gothic style designed by Enrico Alvino.

In 1497, Cardinal Oliviero Carafa decided to add the Succorpo Chapel, a crypt with decorations by Tommaso Malvito, to house the relics of San Gennaro when they were returned to the city. Further restorations were needed after the allied bombing of the Second World War.

The Cathedral Legend:there once stood a large bronze equestrian statue just outside the former cathedral, said to have been magically created by Virgil and endowed with miraculous powers able to heal sick horses. In an attempt to put an end to the superstition, the statue was removed in 1332 by Cardinal Filomarino, who had it melted down to make the bells of the new cathedral.

Highlights Inside the Naples Duomo

The Neapolitan Cathedral is laid out in a Latin cross plan with three naves and several side chapels. The central nave, about 100 meters long and 35 meters high, has a beautiful coffered ceiling with 17th-century paintings. The nave walls are decorated with works by Luca Giordano depicting Apostles, Doctors of the Church, and the patron saints of Naples.

The counter-façade houses the tombs of Angevin rulers including Charles I of Anjou and Carlo Martello, while the transept houses burial markers, bas-reliefs, and sculptures from various eras. The main altar is decorated with bas-reliefs and houses relics of a number of saints.

Basilica di Santa Restituta

Along the left aisle and after the third chapel stands the oldest early Christian basilica in Naples, the Basilica of Santa Restituta. This ancient church dates back to the 4th century and was incorporated into the Cathedral of Naples when it was built almost 1,000 later; it is decorated by 14th-century works by Luca Giordano. The basilica leads to the Baptistery of San Giovanni in Fonte, which may have been built by Emperor Constantine.

The Chapel of the Treasury of San Gennaro

The Chapel of the Treasury sits along the right aisle of the cathedral and houses the relics of San Gennaro (Saint Januarius), including bones and two ampoules containing what is believed to be the saint's blood. The chapel was built in a Greek cross plan by the architect Francesco Grimaldi following the vow made by the Neapolitans to the patron saint during the terrible plague of 1526 and is decorated with ornate frescoes.

Cappella Capece Minutolo

This marvelous Gothic-Angevin chapel is one of the most important in the church. Stop to admire the fourteenth-century triptych and the fabulous mosaic floor.

The Museum of the Treasury of San Gennaro

The Museo del Tesoro di San Gennaro is located next to the Duomo and houses sacred vestments and other objects which, according to tradition, belonged to the patron saint of Naples, plus sacred furnishings and works of art.

The museum’s audio guide was created with the voices and music of famous Neapolitan actors, musicians, and writers, including Toni Servillo, Maurizio de Giovanni, Pietra Montercorvino, and Eugenio Bennato. It is available in several languages, including the Neapolitan dialect.

The Miraculous Liquification of the Blood of San Gennaro

San Gennaro, patron saint of the city affectionately known by the Neapolitans "Face 'Ngialluta" (or “Yellow Face”, from the color of the golden bust of the saint that is carried in procession), was a bishop of Benevento who lived between the 2nd and 3rd centuries. According to tradition, at the martyr’s beheading, a pious woman named Eusebia collected his blood in two ampoules, which today are kept in the safe behind the altar of the Chapel of the Treasury of San Gennaro. Three times a year the archbishop of Naples removes them from the safe during a solemn ceremony and shakes them until the blood miraculously liquefies. This rite is performed in front of a huge crowd of the city’s faithful, municipal authorities, and women believed to be the descendants of Eusebia, who hasten the miracle with song. The Catholic Church has never recognized the phenomenon as miraculous, but it sanctions its popular veneration.

One of the two ampoules is almost full, while the other is almost empty. King Charles of Bourbon took part of the contents with him when he left Italy for Spain to become regent there.

The liquefaction of the blood of San Gennaro is considered by Neapolitans to be a good omen, while the lack of liquefaction is seen as a sign of terrible events to come. According to popular belief, "Yellow Face" also saved the city of Naples from the eruption of Mt. Vesuvius in 1631, when the lava flow stopped right in front of the saint's relics carried in procession on the volcano.

The miracle of liquefaction takes place on the 19th of September, the Saturday before the first Sunday in May, and on the 16th of December. If you intend to attend the ritual, be prepared to face a huge crowd of the faithful, the curious, and unsuspecting tourists. Reach the Duomo early in the morning to find a spot inside and be patient!
