Overview
Sis was the capital of the Armenian Kingdom of Cilicia. The massive fortified complex is just to the southwest of the modern Turkish town of Kozan in Adana Province.
History
In the 3rd millennium B.C. Sis was one of the Hittite settlements on the Cilician plain between the mountains and the Mediterranean coast.
During the 1st century B.C. Sis appears to have been an unfortified village in the Roman province of Cilicia Secunda. The names Sisan or Sisia are first mentioned in the 5th and 6th centuries in Greek and Latin sources. In 703-04 A.D. the Byzantine settlers repulsed an Arab attack, but were soon forced to abandon the town, which became a frontier post for the Abbasid Caliphate. The Caliph Al-Mutawakkil reconstructed the Byzantine defenses in the mid-9th century. The Byzantine Emperor Nikephoros II Phokas recaptured Sis in 962 from the Abbasids, only to have it become an Armenian possession in 1113, when it was occupied by Rubenid Baron T‛oros I and repaired.
From the late 12th through the 13th centuries the castle was significantly enlarged during the reigns of King Levon I and King Het‛um I with a "palace," residential buildings, churches, and gardens. Wilbrand von Oldenburg, a Teutonic monk who visited Sis in 1212, found a complete and well-established capital. Het‛um's wife, Zapēl, is credited with building a hospital there in 1241. A fragment of a dedicatory inscription still in situ within the castle mentions "Het‛um."
