Ankara, historically known with the names Ancyra and Angora, is the capital of Turkey since the empire's fall in 1923 and the country's second largest city, Istanbul being the largest. Centrally located in Anatolia, Ankara is an important commercial and industrial city. It is the center of the Turkish Government, and houses all foreign embassies. It is an important crossroads of trade, strategically located at the centre of Turkey 's highway and railway networks, and serves as the marketing centre for the surrounding agricultural area. The city was famous for its long-haired Angora goat and its prized wool (mohair), a unique breed of cat (Angora cat), Angora rabbits and their prized wool (Angora wool), pears, honey, and the region's muscat grapes.
The historical center of Ankara is situated upon a rocky hill, which rises 150 m (492 ft) above the plain on the left bank of the Ankara Çayı, a tributary of the Sakarya (Sangarius) river. The city is located at about 450 km (280 mi) to the southeast of Istanbul , the country's largest city.
Ankara is a very old city with various Hittite, Phrygian, Hellenistic, Roman, Byzantine, and Ottoman archaeological sites. The hill which overlooks the city is crowned by the ruins of the old castle, which adds to the picturesqueness of the view, but only a few historic structures surrounding the old citadel have survived to the present day. There are, however, many well-preserved remains of Hellenistic, Roman and Byzantine architecture, the most remarkable being the Temple of Augustus and Rome which is also known as the Monumentum Ancyranum.
