Turkey's fourth-largest city (pop. 1,250,000) merits an overnight visit. To enter the city, cross an ancient bridge--in continuous use since Roman legionaries built it in the 2nd century! Once in Adana, head first to the mosques. We think Akca Mescit's pulpit and Eski Cami's restored minaret are especially interesting. Be sure to allow time to see the 19th-century clock towers, the archaeological museum and the Kapali Carsi, or covered market. Day trips from Adana include Tarsus and Karatepe. 240 mi/385 km southeast of Ankara.
