Shasi, a well-known medieval center

Abstract

Shas (also known in historical sources as Suacium, Svač, Soacia, among other variants) represents one of the most significant medieval centers in the wider region of Ulcinj and the Lake Shkodra basin. The site demonstrates a long continuity of settlement beginning in Illyrian antiquity and extending through the Roman, Byzantine, and medieval periods. The ruins of the city are located approximately 25 km northeast of Ulcinj, along the historic Bar–Shkodra route, occupying a strategic hilltop position overlooking Lake Shas. The urban layout closely follows the natural configuration of the terrain and is divided into the Upper Town (fortress) and the Lower Town, a characteristic feature of many medieval settlements in the region. Historical sources mention Shas in official documents as early as 1089, while its bishopric is attested at least from the eighth century. Together with Bar and Ulcinj, Shas formed part of the ecclesiastical organization of the region and belonged to the jurisdiction of the Metropolitanate of Durrës. Archaeological investigations, particularly those conducted in 1989, have confirmed a long cultural and settlement continuity, revealing material remains from the Illyrian, Roman, Byzantine, and medieval periods. The discovery of a cultural layer dating to the sixth century supports the hypothesis that the northern fortification walls were constructed or reconstructed during the reign of Emperor Justinian. The fortress of Shas covered an area of approximately two hectares and was enclosed by defensive walls and towers adapted to the natural terrain. Access to the city was primarily from the northern side, while the southern side was naturally protected by steep and rocky ground. Within the fortification walls, the remains of residential buildings and religious structures have been identified, while outside the walls traces of suburban areas and several churches have been documented. A central place in the urban and ecclesiastical structure of Shas was occupied by the Cathedral of Saint John the Baptist, which served as the episcopal seat of the city. This monument displays significant architectural features, including the integration of the church’s apse into the ground floor of an earlier tower and the functional division of the interior space. In terms of style and monumentality, the cathedral reflects the broader medieval architectural tradition of the western Balkans and shows affinities with important ecclesiastical monuments in the region. Throughout its history, Shas experienced cycles of destruction and recovery. The city was plundered by the Mongols in 1242 but subsequently recovered and continued to function as an urban and ecclesiastical center. From the late fourteenth century onward, however, it entered a period of rapid decline. Following the Ottoman conquest in 1571, Shas lost its urban character and was gradually transformed into a rural settlement. Nevertheless, the surviving ruins and archaeological evidence make Shas an important case study for understanding the historical, religious, and urban development of medieval settlements in the eastern Adriatic hinterland.
