Ankara capital city of Turkey Republic
Ankara is a very old city with various Hittite, Phrygian, Hellenistic, Roman, Byzantine, and Ottoman archaeological sites. The historical centre of town is a rocky hill rising 150 m (500 ft) over the left bank of the Ankara Çayı, a tributary of the Sakarya River, the classical Sangarius. The hill remains crowned by the ruins of the old citadel. Although few of its outworks have survived, there are well-preserved examples of Roman and Ottoman architecture throughout the city, the most remarkable being the 20 BC Temple of Augustus and Rome that boasts the Monumentum Ancyranum, the inscription recording the Res Gestae Divi Augusti.
