İzmir is the third largest city in Turkey with a population of around 3.7 million, the second biggest port after Istanbul, and a very good transport hub. Once the ancient city of Smyrna, it is now a modern, developed, and busy commercial center, set around a huge bay and surrounded by mountains. The broad boulevards, glass-fronted buildings and modern shopping centers are dotted with traditional red-tiled roofs, the 18th century market, and old mosques and churches, although the city has an atmosphere more of Mediterranean Europe than traditional Turkey.
The history of Izmir stretches back to around 3000 BC when the Trojans founded the city in Tepekule in the northern suburb of Bayrakli. This was the birthplace of Homer, who was thought to have lived here around the 8th century BC. The Aeolians, the first greek settlers, were eventually taken over by the (also Greek) Ionians, and then the Lydians destroyed the city around 600BC before a brief recovery following Alexander the Great’s arrival in 334 BC.
After his death, Alexander’s generals followed his wishes and re-established Smyrna on Mount Pagos in Kadifekale, and the city then prospered under the Romans. It was destroyed by an earthquake in 178 AD but later reconstructed and became a major commercial port. After the Byzantines, the city had a turbulent time under the Arabs, Seljuks, Crusaders and Mongols, until Mehmet I incorporated it into the Ottoman Empire in 1415. Under Suleyman the Magnificent, Smyrna became a thriving and sophisticated city and a huge trading center, despite its frequent earthquakes. It was cosmopolitan, with mainly Greek Orthodox and also Jews and Muslims, and many languages were spoken amongst locals and visiting traders.
Following World War I and the defeat of the Ottoman Empire, on the basis of major Greek-speaking population of the area, Greece was granted a mandate over Izmir from the Allies and so Greece took control of the whole Aegean Area. Led by Kemal Ataturk the Turkish army launched a counter-attack and seized the city. Soon thereafter 70% of the city burned to the ground. The big fire ended the multinational era of the city. Ataturk formally took Izmir on 9 September 1922 which is celebrated as the day of city's independence in Izmir.
Dry and sunny summers in Izmir are so infernally hot and sticky that, unless there is an air-con in your room, you will most likely have trouble falling asleep at least on your first night, no matter whether the windows are wide open or not. However, a mild breeze coming in ashore from the sea (locally called meltem) may refreshen the evenings, at least in locations close to the waterfront. Temperature can drop down to freezing point (0°C/32°F) in mostly windy and rainy winters, however snowfall is some sort of curiousness in these latitudes, which happens once or at most twice a decade, if at all.
Izmir has two railway stations: Basmane in the city center serves regional trains and the Metro, and Alsancak in the north serves intercity trains and the IZBAN.
