Silius

Silius is an Italian town located 570 meters above sea level in the eastern part of the Metropolitan City of Cagliari. Part of the historical subregion of Gerrei, the community has seen its population change from 1,384 in 2001 to approximately 984 residents today. The village is characterized by its significant location in the Sardinian hinterland and is bordered by several municipalities including San Nicolò Gerrei and Ballao. Its importance is derived from local landmarks and its industrial history, particularly involving a fluorite mine, making it a point of interest for those exploring the inland areas of the island.

The history of Silius is deeply connected to its strategic standing within the Gerrei region. A major historical landmark is the Castle of Sassai, also referred to as Orguglioso, which underscores the area's significance in medieval times. In addition to its fortified heritage, the town's more recent history has been shaped by the mining industry. The operation of a fluorite mine served as a key economic pillar for the community, significantly influencing both the demographic shifts and the socio-economic evolution of the village over the decades.

Silius is situated at an elevation of 570 meters above sea level in the eastern sector of the Metropolitan City of Cagliari. Situated within the Gerrei subregion, it shares borders with the municipalities of San Nicolò Gerrei, Ballao, Goni, and San Basilio. The geographical setting is defined by its elevated position and proximity to Mont'Ixi, which rises to nearly 800 meters, providing a distinctive landscape characteristic of the southern Sardinian interior.

The natural environment of Silius is highlighted by the Mont'Ixi mountain range. One of the most prominent natural features is the Is Alinos spring, which emerges at an altitude of nearly 800 meters on the slopes of Mont'Ixi. This water source is a vital component of the local landscape. The surrounding area is also defined by its unique geological composition, specifically the presence of fluorite deposits that have shaped the mountainous terrain and regional geography.
