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.
Sigmaringen Castle was first mentioned in the year 1077 in the chronicles of Petershausen monastery. The oldest parts of the castle are concealed beneath the alterations made during the 17th and the 19th centuries. The secret of the earliest settlement built on this defendable rock will never be fully revealed: large-scale excavation work would be necessary, which the extensive land development renders impossible. Judging from the many Roman remains unearthed in the area around Sigmaringen, the 12th century keep known as the 'Roman Tower' could be traced back to a Roman predecessor.
The castle remains that have been preserved (gate, great hall and keep) date back to the Staufer period around 1200. The castle remains were integrated into subsequent buildings. The foundations of the castle buildings are to a large extent identical to the surrounding castle wall.
These remains give us a good idea of how the castle might have looked during the 12th century.
