Ankara is the capital of Turkey, located quite a ways inland in the northern half of the country. It is a very old city, founded in 2000 BC, but was only made into a major city in 1923 when Atatürk made it the capital of his new republic. He chose it because of its location in a place well-protected from invaders. The city is now the political and cultural centre of Turkey and is very cosmopolitan. There are music, ballet, opera, and theatre performances of all kinds, many museums, as well as some prestigious universities and the largest library in Turkey. The most famous musuem is the Musuem of Anatolian Civilizations, and is well worth a visit. Other attractions include the ancient Roman sites and ruins in and around Ankara and historic monuments and buildings such as Kale, the old fortress overlooking the city. The most interesting and charming part of Ankara is Ulus, the old town, which is built on two hills and full of steep, winding streets.
