The Roman Catholic Archdiocese of Naples (Italian: Arcidiocesi di Napoli; Latin: Archidioecesis Neapolitana) is a Roman Catholic Archdiocese in southern Italy, the see being in Naples. A Christian community was founded there in the 1st century AD and the diocese of Naples was raised to the level of an Archdiocese in the 10th century.

Lucio Lemmo and Gennaro Acampa are auxiliary bishops.In the foreword to the Summa Theologica, the famous theological summary of the Catholic Church's doctrines, where a biography of the author, Saint Thomas Aquinas, is found, it is mentioned that he was offered the post of Archbishop of Naples (in the 1200s), which even then was one of the most prominent archdioceses, but turned it down.

The Treasure of San Gennaro is composed of art works and donations collected in seven centuries of Popes, Kings, Emperors, famous and ordinary people, kept in a museum in Naples, Italy. According to studies done by a pool of experts who have analyzed all the pieces of the collection, the Treasure of St. Gennaro would be even richer than the crown of England's Queen Elizabeth II and the Czars of Russia. The Treasure is a collection of art works, kept untouched thanks to the Deputation of the Royal Chapel of the Treasure of San Gennaro, an ancient secular institution founded in 1527 by a vote of the city of Naples, still existing. Today, the donations are exhibited in the Museum, whose entrance is located on the right side of the Cathedral of Naples, under the arcades. By visiting the Museum, you can access the Royal Chapel of San Gennaro, where the two ampules containing San Gennaro's Blood are kept in the Major altar. The museum was opened in December 2003 thanks to a project funded by private companies, European funds and local institutions under the patronage of the President Ciampi, on a proposal of the Deputation of the Chapel of the Treasure of San Gennaro, (established in 1601). The curator of the project was the director Paolo Jorio.

Santa Restituta is a church in Naples, southern Italy, dedicated to Saint Restituta. The foundation of the basilica is attributed to the Emperor Constantine the Great in the 4th century and is mentioned in a passage from the life of Pope Sylvester I in the Liber pontificalis: "[...] at that time, the emperor Constantine built a basilica in the city of Naples." The basilica is most likely located on the site previously occupied by an ancient temple of Apollo.It is the original palaeo-Christian church on the site where the Cathedral of Naples now stands, and was rebuilt and incorporated into the cathedral when it built in the 13th century. In the crypt are archaeological remains: a Greek wall, belonging to the temple of Apollo, in opus reticulatum. Under the apse the peristyle of a late imperial domus was found, whose peristyle is still evident. Also a stretch of Roman aqueduct after the foundation of the city and a stretch of Greek road on an inclined plane. Santa Restituta has a nave with two aisles divided by 27 antique columns, and forms a large, separate part of the cathedral.

The Pio Monte della Misericordia is a church in the historic center of Naples, southern Italy. It is famous for its art works, including Caravaggio's The Seven Works of Mercy. A charity brotherhood (Pio Monte della Misericordia meaning "Pious Mount of Mercy" in Italian) was founded in August 1601 by seven young nobles, who met every Friday at the Hospital for Incurables and ministered to the sick.In 1602 they established an institution and commissioned a small church, built by Gian Giacomo di Conforto, near the staircase leading to the Cathedral, on the corner of the Via dei Tribunali and the Vico dei Zuroli. In 1605, they received an apostolic letter from Pope Paul V, according special privileges to the high altar.The church was consecrated in September 1606. From 1658 to 1678 the edifice was enlarged, also with the annexation of neighbouring structures, by architect Francesco Antonio Picchiati, forming a complex with a palace and a renewed church. The latter, at the high altar, houses Caravaggio's Seven Works of Mercy. There are also paintings by Luca Giordano, Carlo Sellitto, Fabrizio Santafede, Battistello Caracciolo and others. The noblemen of the brotherhood at Pio Monte della Misericordia were looking for painters "to give permanent visual expression to their sense of charitable mission”. Regarding the sharp contrasts of the chiaroscuro in Caravaggio's painting’s, the German art historian Ralf van Bühren explains the bright light as a metaphor for mercy, which "helps the audience to explore mercy in their own lives".

The Archbishop's Palace (Italian: Palazzo Arcivescovile) is a building in Naples, Italy. It is the official residence of the Archbishop of Naples. The building is located on the square largo Donna Regina one block north of the Cathedral of Naples directly across from the church of Donna Regina Nuova. Together, the cathedral and the Archbishop's Palace form a vast, connected complex. The original structure was built in 1389 at the wishes of Cardinal Archbishop Enrico Capece Minutolo on the site of an old early Christian basilica. The building seen today, however, is largely the result of reconstruction and expansion of the premises under Cardinal Archbishop Ascanio Filomarino, completed in 1654. That reconstruction was most probably the work of architect Bonaventuri Presti. The expansion included the clearing of the area directly in front of the building to create a small open square between the Archbishop's Palace and the church of Donna Regina Nuova. The building has an elongated shape and is marked by three stone portals.

The Diocesan Museum is the museum of the Roman Catholic Diocese of Naples, displaying paintings, reliquaries and bronzes previously housed in the Archepiscopal Palace, closed and suppressed churches in the Diocese (such as the churches of Santa Donna Regina Nuova and the neighbouring Santa Maria Donnaregina Vecchia) or churches where it is too risky to display artworks. The paintings are mainly from the Neapolitan School, including works by Luca Giordano, Francesco Solimena, Massimo Stanzione, Aniello Falcone and Andrea Vaccaro. It was originally housed in the Archepiscopal Palace but due to an initiative by cardinal-archbishop Crescenzio Sepe it re-opened in the rooms behind the chancel of Santa Donna Regina Nuova and on a new mezzanine floor above the side chapels of its nave on 23 October 2007. The rooms above the side chapels are organised thematically, with a room each for the Passion of Christ, the Seven Sacraments, Martyrdom, the Life of Priests, Monks and Mendicants and the Seven Works of Pity. Other rooms house objets-d'art, such as two bronzes of St Candida of Naples and St Maximus by Giovan Domenico Vinaccia from Naples Cathedral, reliquaries, vestments and sculptures in wood and stone. Visitors can also see the neighbouring Santa Maria Donnaregina Vecchia, although this does not display any artworks from the collection. Santa Donna Regina Nuova belongs to the Ministry of the Interior's "Collection of religious buildings", whilst the City of Naples owns Santa Maria Donnaregina Vecchia. The museum is managed by the Archdiocese and supervised by the Soprintendenza al polo museale di Napoli.
