Vassallaggi is a Sicilian prehistoric Bronze Age archaeological site which had a later flourishing after the 7th century BC as a phrourion (fortress). The site is located in the middle of the Salso river valley, at 704 m above sea level, in a strategic location for communication between the southern coast of Sicily and the northern part of the island.
The site first developed in the Bronze Age (18th-14th centuries BC), from which time some cave tombs of the Castelluccio culture survive and a circular hut with furniture. The most ancient inhabitants of Vassallaggi were presumably the Sicans.
No finds have come to light from the middle and late Bronze Age, so these hills may have been abandoned at that time; this might be a result of emigration towards the coast from the middle Bronze Age and then as a result of the preference for more defensible sites in face of the arrival of the Sicels (which might have taken the form of an invasion). Thus the site was unoccupied for about 700 years, before a Sican settlement developed here in the 8th century BC.
This new habitation during the Iron Age continued until Greek occupation of the site in the 5th century, when the village seems to have been fortified and to have developed within the sphere of Akragas.
After the foundation of that city by Gela (most powerful of the Dorian colonies founded in the 7th century BC), a period of expansion of Greek origin people began which led to the colonisation of central Sicily, using the natural route along the Himera river valley (the modern Salso). The expansion into inland Sicily may be explained by the demographic pressure on the Greek communities of the motherland and the other Greek colonies. The need to augment agricultural production and open new markets for manufactured goods may also have been a causal factor.
The site of Vassallaggi, however, based on archaeological evidence, was only conquered and colonised by Greeks from Akragas in the 6th century BC, unlike nearby sites, like Sabucina, Capodarso and Gibil Gabib which were colonised by Gela, as shown by the proto-Corinthian style pottery found there, which is never found at Vassallaggi.
The most important discoveries in the rich necropolis, both in terms of quantity and quality of items recovered, derive from this period. They include ceramic sarcophagi, one of which is perfectly preserved, locally-made vases, pottery from other Greek areas, bronze knives, spears and strigils, as well as coins. A temple for the worship of a female deity was built at this time.
The absence of concrete evidence makes it difficult to attribute any known ancient place name to the location. It has been suggested that the site is Motyon, the first fortified centre in the Acragantine area. The city was inexplicably abandoned around 320 BC. There are no traces of objects after this date.
From the Roman period, traces of small nucleated settlements are found in the valley and the surrounding territory, including especially important routes to Akragas. Christian tombs, dating to the 5th century AD have been found, near the prehistoric caves.
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.
