Location and Structural Features

Gülek Castle is situated on a dominant hilltop approximately 2 km southwest of the Gülek Pass. Its northern and northeastern sides are bordered by natural cliffs, eliminating the need for additional fortifications in those directions. Access to the castle is via a monumental gate on the southern side, while the southern and west walls are clearly visible. These walls are reinforced with circular or square plan towers of varying sizes. At the castle’s farthest end lies a cistern, and its walls incorporate ashlars with bossed surfaces characteristic of the Cilician Armenian Kingdom period. Aside from the structure adjacent to the entrance gate, very few other buildings remain standing within the compound. Surface surveys reveal prominent fragments of glazed or unglazed ceramic pottery in yellow and green colors.

The slopes of the rocky hill on which the castle stands are covered with cedar trees, while the base consists of mixed limestone rocks that rise in layered formations toward the upper sections. Alishan (1899) recorded the discovery of fossilized marine organisms of the genus Echinites sea and various coral species in the area. Additionally, remnants of an ancient altar carved into the rock face on the western cliff and traces of two illegible inscriptions have been identified.

Historical Significance

The strategic importance of Gülek Castle stems from its role as a military complex guarding the Tarsus Road (Via Tauri) and the Cilician Gates. During the Middle Ages, travelers passing through the Gülek Pass were required to pay tolls to the castle’s commander, underscoring its economic and military value. Historical records indicate that the castle was either constructed or substantially renovated during the period of the Cilician Armenian Kingdom. In the 1198–1199 tax list, the name Smbat appears as Lord of Gülek, and the fortress is referred to at that time as Asakaliba. Its continuous occupation over centuries is evident from its architectural structure and material finds.

In 1432–1433, the traveler who visited the region referred to the castle as Cublech and described it as “the highest castle he had seen up to that point.” Evliya Çelebi, in the 17th century, described the fortress as “rising to the heavens” and noted its location in the Ramazanoğlu Yaylası area within the Kusun kazas. It is known that in 1838–1839, Ibrahim Pasha occupied the castle during his rebellion against Ottoman rule. During this period, a lead mine was recorded on the northwestern side of the fortress, and the masonry on the southern and western walls showed similarities to fortifications built in Pozantı during the late 1830s.
