Set amid amazing scenery of sharp contrasts, Antalya, Turkey's principal holiday resort, is an attractive city with shady, palm-lined boulevards and a prize-winning marina. In the picturesque old quarter, Kaleiçi, narrow, winding streets and old wooden houses abut the ancient city walls. Since its founding in the second century BC by Attalos II, a king of Pergamon, who named the city Attaleia after him, Antalya has been continuously inhabited. The Romans, Byzantines and Seljuks successively occupied the city before it came under Ottoman rule. The elegant, fluted minaret of the Yivli Minareli Mosque in the center of the city, built by the Seljuk sultan Alaeddin Keykubat in the 13th-century, has become Antalya's symbol. The Karatay Medrese (theological college) in the Kaleici district, from the same period, exemplifies the best of Seljuk stone carving. The two most important Ottoman mosques in the city are the 16th-century Murat Pasa Mosque, remarkable for its tile decoration, and the 18th-century Tekeli Mehmet Pasa Mosque
