The National Archaeological Museum of Naples is an important Italian archaeological museum, particularly for ancient Roman remains. Its collection includes works from Greek, Roman and Renaissance times, and especially Roman artifacts from nearby Pompeii, Stabiae and Herculaneum.
The building was built as a cavalry barracks in 1585. From 1616 to 1777 it was the seat of the University of Naples. During the 19th century, after it became museum, it suffered many changes to the main structure.
The museum hosts extensive collections of Greek and Roman antiquities. Their core is from the Farnese Collection, which includes a collection of engraved gems (including the Farnese Cup, a Ptolemaic bowl made of sardonyx agate and the most famous piece in the 'Treasure of the Magnificent', and is founded upon gems collected by Cosimo de' Medici and Lorenzo il Magnifico in the 15th century) and the Farnese Marbles. Among the notable works found in the museum are the Herculaneum papyri, carbonized by the eruption of Mount Vesuvius, found after 1752 in Villa of the Papyri.
The greater part of the museum's classical sculpture collection largely comes from the Farnese Marbles, important since they include Roman copies of classical Greek sculpture, which are in many cases the only surviving indications of what the lost works by ancient Greek sculptors such as Calamis, Kritios and Nesiotes looked like. Many of these works, especially the larger ones, have been moved to the Museo di Capodimonte for display in recent years.
The museum's Mosaic Collection includes a number of important mosaics recovered from the ruins of Pompeii and the other Vesuvian cities. This includes the Alexander Mosaic, dating from circa 100 BC, originally from the House of the Faun in Pompeii. It depicts a battle between the armies of Alexander the Great and Darius III of Persia. Another mosaic found is that of the gladiatorial fighter depicted in a mosaic found from the Villa of the Figured Capitals in Pompeii.
With 2,500 objects, the museum has one of the largest collection of Egyptian artifacts in Italy after the Turin, Florence and Bologna ones. It is made up primarily of works from two private collections, assembled by Cardinal Stefano Borgia in the second half of the 18th century, and Picchianti in the first years of the 19th. In the recent rearrangement of the galleries the two nuclei have been exhibited separately, while in the connecting room other items are on display, including Egyptian and 'pseudo-Egyptian' artefacts from Pompeii and other Campanian sites. In its new layout the collection provides both an important record of Egyptian civilization from the Old Kingdom (2700-2200 B.C.) up to the Ptolemaic-Roman era.References:
The Petersberg Citadel is one of the largest extant early-modern citadels in Europe and covers the whole north-western part of the Erfurt city centre. It was built after 1665 on Petersberg hill and was in military use until 1963. It dates from a time when Erfurt was ruled by the Electors of Mainz and is a unique example of the European style of fortress construction. Beneath the citadel is an underground maze of passageways that can be visited on guided tours organised by Erfurt Tourist Office.
The citadel was originally built on the site of a medieval Benedictine Monastery and the earliest parts of the complex date from the 12th century. Erfurt has also been ruled by Sweden, Prussia, Napoleon, the German Empire, the Nazis, and post-World War II Soviet occupying forces, and it was part of the German Democratic Republic (East Germany). All of these regimes used Petersberg Citadel and had an influence on its development. The baroque fortress was in military use until 1963. Since German reunification in 1990, the citadel has undergone significant restoration and it is now open to the public as a historic site.
