Beside the Sumbas Cayi, near the village of Anavarza in Upper Cukurova, to the east of the Ceyhan-Kozan road, lie the easily recognized walled ruins of Anazarbus, at one time the minor capital of Lesser Armenia. Perched dizzily on an isolated crag some 200m/650ft directly above the town (and reached by steps from near the theater) are extensive remains of the fortress (upper and lower fort). in addition to the ancient main street other town ruins include a Roman stadium, a theater, an aqueduct, several churches and a fine gate to the south.
The local open-air museum (situated away from the site itself, in the center of the village) has some famous mosaics from the third century.
Founded in the first century B.C. Anazarbus was a Romano-Byzantine town. in the 12th century, after numerous disputes with Byzantium and with the aid of the Crusaders, it passed to Lesser Armenia, the principal capital of which was Sis (Sisium/Kozan). Although from 1199 onwards the Armenian princes styled themselves kings, they were always forced, in the final resort, to acknowledge Byzantine supremacy. While close links between the royal house and the Mongols preserved Anazarbus from destruction, in 1297 a Mongol prince had 40 Armenian noblemen, together with Hetum their king, murdered at a banquet in the town.
