Kormas (İncekaya) Castle

Kormas Castle, also known as İncekaya Castle, is a place structure located in İncekaya (Kormas) Village of the Şirvan district in Siirt province, historical on a castle site. Dating to the Byzantine period, this castle exemplifies the archaeological and architectural heritage of southeastern Anatolia Turkey. Situated on a hill commanding the surrounding landscape, approximately 10 kilometers from the Şirvan district center, the castle stands out as a building designed for both defense and surveillance. This article examines the location, architectural features, and current condition of Kormas Castle using only the provided texts, in an objective and academic style.

Kormas Castle is located in İncekaya (Kormas) Village of the Şirvan district in Siirt province, approximately 10 kilometers from the district center. The castle is situated on a hill that dominates the surrounding terrain, a strategic feature that supports its defensive function. Located within the boundaries of Siirt province in southeastern Turkey, the castle is identified as an accessible site under culture tourism. Access to the castle can be achieved by following a route from Şirvan district center toward İncekaya Village. Although the address is listed simply as “Siirt,” the castle’s complete location is specifically associated with İncekaya Village.

Kormas Castle was constructed as a defensive structure during the Byzantine period. While texts describe the castle as resembling a castle more than a fortress, this characterization reflects a general impression of its appearance rather than its specific architectural traits. The structure extends in a northeast-southwest direction, adapting to the topography of the hill and incorporating natural features into its design. The walls, reinforced by towers on three sides, rest against a natural rock formation on the fourth side. This arrangement demonstrates the integration of natural and artificial elements to enhance both structural integrity and defensive capacity.

The castle walls are constructed of rubble stone, debri, and regularly cut stone. Supported by a total of seven towers, the walls consist of six semicircular and one rectangular tower; the variation in tower sizes indicates functional diversity in the castle’s design. Two cisterns carved directly into the rock are located at the entrance; these cisterns were likely planned to ensure a water supply during prolonged defensive situations. The majority of internal structures lie buried beneath the earth, with only a limited number of sections remaining partially standing. The surviving portions are built of rubble stone and covered with barrel vaults. The use of barrel vault vaults is a characteristic feature of Byzantine architecture, common enhancing the structure’s durability through technical engineering principles.

The castle is described as being in a ruined state, indicating that the structure has suffered from natural degradation and neglect within its time environment. Nevertheless, the partial preservation of walls and towers allows for the recognition of its original plan and architectural features. The publication Ottoman Period Monuments in Pervari and Şirvan by Ali Boran, Abdülhamit Tüfekçioğlu, İrfan Yıldız, and Zekai Erdal (work, Ankara, 2009, pp. 66–74) is referenced; however, although this source explicitly identifies the castle as Byzantine in origin, it does not emphasize a direct connection to the Ottoman period.^【1】 

Today, Kormas Castle remains accessible and is included among sites of cultural tourism. Although the castle presents a largely ruined appearance, its surviving towers and walls continue to attest to its historical presence. The fact that the majority of internal structures lie buried beneath the earth and only limited sections remain partially standing indicates severe physical deterioration. Nevertheless, as a defensive structure dating to the Byzantine period, the castle retains its archaeological and historical significance.
