Ankara
Ankara has been the capital of Turkey since October 13, 1923, and with approximately 5.9 million inhabitants, it is the country's second-largest city after Istanbul. Here you'll find Atatürk's Mausoleum and the Museum of Anatolian Civilizations, featuring artifacts from the Hittite era; by high-speed train, you're about four hours from Istanbul. The old town of Ulus, with its Citadel and Hamamönü, is located in the north, while the modern center Kızılay and the nightlife streets around Tunalı Hilmi and Kavaklıdere are further south.
