土耳其西北部港市-伊斯坦布尔
Istanbul (Turkey)

The Bosphorus, the strait flowing between the Sea of Marmara and the Black Sea, creates a natural north-south divide in Istanbul - European Istanbul comprises the bulk(大部分)of the city to the west, while Asian Istanbul is to the east. European Istanbul is itself divided by the Golden Horn into the Old City to the south, and Beyoglu and other modern districts to the north.

The Old City is where you'll find all the main sights, such as Topkapi Sarayi (Topkapi Palace), Sultan Ahmet Camii (Blue Mosque), Aya Sofya (Sancta Sophia), the Atmeydani (Hippodrome) and the old city walls. The 21st-century version of Istanbul is a short walk north across the Galata Bridge, and is exemplified by bustling Taksim Square, the eye of the city's commercial storm. Buses, trams and the developing Metro system, not to mention footpower, will get you around the two main parts of the city - ferries(渡轮)can run you between them and across the Bosphorus to Asian Istanbul, although there's little of interest for tourists in this suburban area.
