The Naples National Archeological Museum has one of the best collections of classical Greek and Roman art in the world. Most of the exhibits are from excavations around Naples, Pompeii and Herculaneum.
The Naples National Archeological Museum occupies a building that was constructed to house the cavalry barracks of the Spanish army. Between 1616 and 1777, it was the seat of the University of Naples. The building became the Royal Bourbon Museum in 1816. It housed exhibits and artwork collected by the Royal family, a library and archeological objects. The library and art gallery were relocated to other buildings in 1957. The present museum is solely dedicated to exhibiting objects from archeological excavations.
Collections at the Naples National Archeological Museum include mosaics from portions of walls and floors of buildings in Pompeii, Herculaneum and Stabiae, frescoes from Pompeii some of which are the finest examples of classical Roman art, a collection of 200,000 coins and medals, paintings from the temple of Isis in Pompeii and the third largest collection of Egyptian artifacts in Italy. The Secret Cabinet within the museum is a room created to display Roman erotic art that is open only to visitors above the age of eleven years.

The Human Anatomy Museum is located at the Via Armanni in Naples. Its main attractions are wax models of different parts of the human body.
King Ferdinand IV ordered that all anatomy exhibits belonging to the University of Naples and the hospital, called the Ospedale di San Giacomo Apostolo, be transferred and placed in the university’s Zoology Cabinet. Francesco Folinea was the first director of the cabinet. He was succeeded by Antonio Nanula, an eminent professor of anatomy, who expanded the number of objects displayed and added his own personal collection, including specimens dried in alcohol. He commissioned the sculptor, Francesco Saverio Citarelli, to make the wax sculptures for which the museum is well known. The building, housing the museum, was damaged during the Second World War and, later, by a devastating earthquake in 1980. After extensive restorations that lasted over 10 years, it opened again in the year 1997.
The main exhibits at the Human Anatomy Museum are Citarelli’s wax sculptures of different parts of the human body. The museum also has a section of human organs, including the brain, kidneys, stomach and parts of the intestines preserved in formalin and alcohol. There is a separate section for organ malformations with preserved ill formed fetuses, double fronted and cyclopean one eyed heads. Entrance to the museum is free. It stays open on weekdays and is closed on weekends.

The Treasure of Saint Gennaro Museum displays the wealth of offerings made by popes, aristocrats and the common people to the patron saint of Naples, St. Januarius. It is located within the grounds of the principal cathedral of the city.
The Treasure of Saint Gennaro Museum was opened to the public in 2004. At first, the idea of setting up the museum met with resistance from the local people who felt that displaying the treasure for all to see was irreverent to their patron saint. Its planning took eight years and after another seven years the entire collection was displayed.
The Treasure of Saint Gennaro Museum has over 25 display cases with artifacts made of bronze, silver and gold. Each is a work of art, showing the brilliant craftsmanship of Neapolitan sculptors and metalworkers. The earliest object on display is from the 1300s. Most of the exhibits were crafted in the 1600s and the most recent one is from the early 1900s. There are bronze busts of the saint, crucifixes, religious objects made of silver, including chalices, candelabras, plates and other liturgical exhibits, a two foot tall miter, covered with emeralds and rubies, and the necklace of Saint Gennaro, hung with crosses containing sapphires and rubies. Audio guides are included in the price of the entrance ticket for the benefit of international visitors.

The Excavations of San Lorenzo Maggiore show a complete Roman forum and earlier Greek Agora. They are located under the church of San Lorenzo Maggiore. The site was opened to the public after 25 years of painstaking work by archeologists.
The excavations of San Lorenzo Maggiore have revealed a wealth of details about the city of Naples in classical times. The site of Piazza San Gaetano near the church was once a Greek Agora or marketplace. Later, it became a Forum or Roman marketplace. Excavations have also revealed the great hall and three naves of a sixth century paleo-Christian church. Under the Sala Capitolare of the San Lorenzo Maggiore church are the medieval city halls. The excavated area has been opened to the public since 1992.
The excavations of San Lorenzo Maggiore are the only complete excavations around Naples. They show life in the city through the ages. Only half of the original Roman forum has been excavated and visitors can view it by entering the marked gate near the entrance of the church. One can see a whole ancient street from the 4th century BC complete with workshops, laundries and the public treasury. Most of the objects from the archeological finds are at a nearby museum, housed in a converted four story Palazzo.

The Museo Cappella Sansevero has works by leading 18th century artists and a unique anatomical exhibit. It was once the funerary chapel of the Sansevero family and lies within the grounds of their residence.
The Cappella Sansevero was built in 1590 by John Francesco di Sangro, Duke of Torremaggiore in gratitude for recovering from a serious illness. It was converted in 1613 as the family burial chapel by Alessandro di Sangro. Prince Raimondo di Sangro of Sansevero remodeled the funerary chapel in the 18th century to house his collection of art and unique objects. Until 1888, his residence and the chapel were connected by a passage. He was also an inventor and alchemist. Many of the works in the museum are made with a marble like substance created by him.
The Museo Cappella Sansevero has over 30 valuable pieces of art. The ceiling fresco called Glory of Paradise was painted by Francesco Maria Russo. The marble like substance was used to create the Cristo Velato or veiled Christ and the Pudicizia depicting a veiled woman on the tomb of Raimondo’s mother by Giuseppe Sanmartino. The Madonna con Bambino, a painting in the basement by artist Giuseppe Pesce is worked using specially created wax paints invented by Raimondo. The popular exhibits are two human skeletons located in the crypt of the chapel. One is of a male and another of a pregnant female with perfectly preserved circulatory systems.

The Zoological Museum is a teaching and research facility attached the University of Naples. It has some unique natural history exhibits on display.
The Zoological Museum of Naples was founded by Gioacchino Napoleone Murat, Napoleon’s brother in law and King of Naples between 1808 and 1815. The museum opened its doors in 1811 with Luigi Petagna as its first curator. It housed the natural history collections of the Royal House of Bourbon and the private collection of eminent physician, Giuseppe Saverio Poli. The building housing the museum was severely damaged during World War II. It was restored under the capable guidance of curator, Mario Salfi, between 1948 and 1970.
The donation of the collection of natural history exhibits by physicist and natural historian Giuseppe Saverio Poli greatly enriched the displays at the Zoological Museum. The collection includes rare species of southern European butterflies, fresh water and marine mollusks and marine organisms and sponges unique to the Mediterranean Sea. Other exhibits are from the royal collection with over 3,000 embalmed birds, a collection of vertebrates including the skeleton of a 20 meter long whale found on the beach of Naples, mummified crocodiles from Egypt and the skeleton of an elephant. Guides are available at the museum for the convenience of international visitors.
