Eminönü is a district of Istanbul in Turkey. This is the heart of the walled city of Constantine, the focus of a history of incredible richness. Eminönü covers the point on which the Byzantine capital was built. The Galata Bridge crosses the Golden Horn into Eminönü and the mouth of the Bosphorus opens into the Marmara Sea. And up on the hill standsTopkapı Palace, the Blue Mosque (Sultanahmet Camii) and Hagia Sophia (Aya Sofya). Thus Eminönü is the main tourist destination in Istanbul. It was a part of the Fatih district until 1928, which covered the whole peninsular area of old Istanbul within the medieval city walls - that area which was formerly the Byzantine capital Constantinople. Since the resident population of Eminönü is low today, it is scheduled to rejoin the Fatih district.
Istanbul (historically Byzantium and later Constantinople; see the other names of Istanbul) is the largest city of Turkey and the third largest city in the world. The city covers 27 districts of the Istanbul province.It is located on the Bosphorus Strait and encompasses the natural harbor known as the Golden Horn, in the northwest of the country. It extends both on the European (Thrace) and on the Asian (Anatolia) side of the Bosphorus, and is thereby the only metropolis in the world which is situated on two continents. In its long history, Istanbul served as the capital city of the Roman Empire (330–395), the East Roman (Byzantine) Empire (395–1204 and 1261–1453), the Latin Empire (1204–1261), and the Ottoman Empire (1453–1922). The city was chosen as joint European Capital of Culture for 2010. The historic areas of Istanbul were added to the UNESCO World Heritage List in 1985.
