Rising dramatically on a steep incline from the banks of the Enguri Su, Ankara, Turkey's capital and second most populous city, is a modern European metropolis speckled with reminders of its varied history. Old castles and ruins from Hittite, Phrygian, Hellenistic, Roman, Byzantine, and Ottoman civilizations dot the landscape. The modern city includes government and state houses, major universities, military bases, consulates, bustling nightlife and the oldest park in the city, Genclik Park.
