๐๏ธ The Church of Santa Maria: A Romanesque Jewel in the Heart of Sulcis
In the enchanting territory of Carbonia, precisely in the locality of Flumentepido, stands a small but extraordinary testimony to Sardinian Romanesque architecture: the rural church of Santa Maria. This church is notable for the Roman milestone dedicated to Emperor Vespasian. This enhances its historical value. However, this sacred building guards an archaeological secret of exceptional value that goes far beyond its religious and architectural importance.

Built in the 11th century in Romanesque architectural style with a simple “barn-like” structure, the church has a single nave without apse. It also features a facade topped by a small bell gable. These characteristics are typical of Sardinian medieval religious architecture. Furthermore, the small church had been built on the summit of Flumentepido hill by the Victorine monks, who left numerous testimonies of their presence in the Sulcis area.
The strategic position of the church is not casual. It is located on the summit of a hill, in a panoramic position. The design is characterized by a longitudinal plan with a single nave, without apse. Therefore, this privileged location offers visual control over all the surrounding territory. This characteristic will prove fundamental to understanding the presence of the site’s most precious archaeological element.

๐ฟ Vespasian’s Milestone: A Column of History
The true peculiarity that makes the church of Santa Maria in Flumentepido unique is the presence of an authentic Roman milestone from the time of Vespasian. This milestone is used as a structural element of the religious building. This extraordinary archaeological artifact represents direct testimony to the Roman presence in Sardinia and, specifically, to the route of the ancient Via Sulcitana.
The milestone, perfectly preserved despite the centuries that have passed, still presents clearly visible inscriptions. These inscriptions certify its authenticity and historical importance. Furthermore, the writings carved in stone tell of an era when Sardinia was perfectly integrated into the road system of the Roman Empire. It was connected through an efficient road network that guaranteed military control and economic development.
Consequently, the presence of this milestone is not just an archaeological curiosity. It represents tangible proof of the strategic importance that this territory held in antiquity. Indeed, its position along the route of the Via Sulcitana made it a fundamental reference point for travelers and Roman troops who traveled this important communication artery.
๐ค๏ธ Roman Milestones: Silent Witnesses of Imperial Roads
Roman milestones constitute one of the most concrete and fascinating testimonies to the territorial organization of the Roman Empire. The ancient Romans built long roads to connect the most distant provinces with the empire’s capital, constructed as straight as possible to minimize distances. Consequently, these stone elements served a fundamental practical function, indicating distances from major cities and providing essential information to travelers.

Furthermore, milestones were not simple road indicators, but true monuments that celebrated imperial power and the efficiency of Roman administration. Therefore, each inscription present on these markers represented a declaration of sovereignty and territorial control. They testified to the presence of imperial authority even in the most remote provinces.
Vespasian’s milestone present at Flumentepido therefore assumes exceptional value. It represents not only an archaeological artifact, but also a historical document that certifies the importance of this territory in Roman economy and military strategy. Indeed, its presence along the Via Sulcitana demonstrates how this road was considered strategically relevant for the Empire.
Consequently, the study of these stone monuments allows archaeologists to accurately reconstruct the routes of ancient Roman roads. It also helps to understand the organization of territory in the imperial era.

๐ฃ๏ธ The Via Caralibussulcos: Strategic Artery of Ancient Sulcis
The Via Sulcitana, also known as Via Caralibussulcos, represented one of the most important road arteries of Roman Sardinia. This road, approximately 60 kilometers long, connected Carales (modern-day Cagliari) with Sulki (Sant’Antioco), crossing territories of fundamental strategic and economic importance for the island.
Furthermore, the route followed a path designed to optimize connections between the main urban centers and the mining sites of Sulcis-Iglesiente. These areas were rich in precious metals that constituted one of the main sources of wealth of Roman Sardinia. Therefore, this road did not only serve as a connection between cities. It also represented a vital economic infrastructure for the exploitation of the island’s mineral resources.
The construction of the Via Caralibussulcos followed Roman engineering standards. It had a route as straight as possible and paving in local stone that guaranteed passability in all weather conditions. Consequently, milestones and rest stations were positioned along its route. They facilitated travel and provided services to travelers and commercial caravans.
The territory crossed by the road included areas of great agricultural fertility and zones rich in natural resources. These factors made this road connection essential for the economy of the entire region. Indeed, the road allowed rapid and efficient transport of agricultural products to Cagliari and extracted metals to the ports of embarkation for Rome.
