The Catacombs of San Gennaro are underground paleo-Christian burial and worship sites in Naples, Italy, carved out of tuff, a porous stone. They are situated in the northern part of the city, on the slope leading up to Capodimonte, consisting of two levels, San Gennaro Superiore, and San Gennaro Inferiore.
Originally, there were three separate cemeteries, dedicated, to Saint Gaudiosus (San Gaudioso), Saint Severus (San Severo) and St. Januarius (San Gennaro). These catacombs in Naples are different from their Roman counterparts in that they have more spacious passageways along two levels. The lower level is the oldest, going back to the 3rd-4th century and may actually be the site of an earlier pre-Christian cemetery later ceded to the new sect. It apparently became an important religious burial site only after the entombment there of Bishop Agrippinus. The second level was the one expanded so as to encompass the other two adjacent cemeteries.
The foundation of San Gennaro extra Moenia church is connected with the catacombs. The first structure was probably the result of the fusion of two ancient burial sites, one from the 2nd century CE that contained the remains of Saint Agrippinus of Naples, the first patron saint of Naples, and the site from the 4th century CE that contained the remains of St. Januarius, the patron saint of the city.
The site was consecrated to Gennaro (Januarius) in the fifth century on the occasion of the entombment there of his remains, which were later removed to the Cathedral of Naples by Bishop John IV (842-849) in the 9th century. As the burial areas grew around the remains of Gennaro so did underground places of worship for the growing Christian faith. An early example of religious use of the catacombs is the Basilica of Agrippinus dating to the fourth century. An altar and chair are carved from the tuff creating a meeting place for worshipers. Other ritual spaces included a confessional, baptismal font, a carved tuff table used as a seat for a consignatorium (area for confirmation), or oleorum table for holy oils, and possibly, monastic and hermit cells.
Until the eleventh century the catacombs were the burial site of Neapolitan bishops, including Quodvoltdeus, the exiled bishop of Carthage who died in 450 AD. Between the 13th and 18th century, the catacombs were the victim of severe looting. Restoration of the catacombs was made possible only after the transfer of skeletal remains to another cemetery. During WWII the catacombs were used by the local population as a place of shelter. The Catacombs were reopened in 1969 by the Archbishop of Naples and modern excavations started in 1971.References:
Royal Palace of Naples was one of the four residences near Naples used by the Bourbon Kings during their rule of the Kingdom of the Two Sicilies (1734-1860): the others were the palaces of Caserta, Capodimonte overlooking Naples, and the third Portici, on the slopes of Vesuvius.
Construction on the present building was begun in the 17th century by the architect Domenico Fontana. Intended to house the King Philip III of Spain on a visit never fulfilled to this part of his kingdom, instead it initially housed the Viceroy Fernando Ruiz de Castro, count of Lemos. By 1616, the facade had been completed, and by 1620, the interior was frescoed by Battistello Caracciolo, Giovanni Balducci, and Belisario Corenzio. The decoration of the Royal Chapel of Assumption was not completed until 1644 by Antonio Picchiatti.
In 1734, with the arrival of Charles III of Spain to Naples, the palace became the royal residence of the Bourbons. On the occasion of his marriage to Maria Amalia of Saxony in 1738, Francesco De Mura and Domenico Antonio Vaccaro helped remodel the interior. Further modernization took place under Ferdinand I of the Two Sicilies. In 1768, on the occasion of his marriage to Maria Carolina of Austria, under the direction of Ferdinando Fuga, the great hall was rebuilt and the court theater added. During the second half of the 18th century, a 'new wing' was added, which in 1927 became the Vittorio Emanuele III National Library. By the 18th century, the royal residence was moved to Reggia of Caserta, as that inland town was more defensible from naval assault, as well as more distant from the often-rebellious populace of Naples.
During the Napoleonic occupation the palace was enriched by Joachim Murat and his wife, Caroline Bonaparte, with Neoclassic decorations and furnishings. However, a fire in 1837 damaged many rooms, and required restoration from 1838 to 1858 under the direction of Gaetano Genovese. Further additions of a Party Wing and a Belvedere were made in this period. At the corner of the palace with San Carlo Theatre, a new facade was created that obscured the viceroyal palace of Pedro de Toledo.
In 1922, it was decided to transfer here the contents of the National Library. The transfer of library collections was made by 1925.
The library suffered from bombing during World War II and the subsequent military occupation of the building caused serious damage. Today, the palace and adjacent grounds house the famous Teatro San Carlo, the smaller Teatrino di Corte (recently restored), the Biblioteca Nazionale Vittorio Emanuele III, a museum, and offices, including those of the regional tourist board.
