Istanbul

Istanbul is Turkey’s exotic capital, a riot of colour, culture and magnificent old buildings. Visitors will be awestruck by the Hagia Sophia museum, the Blue Mosque and the remarkable Byzantine Hippodrome. Istanbul’s Grand Bazaar is one of the largest and oldest covered markets in the world, boasting over 4,000 shops selling everything from carpets to caviar.

Istanbul; is the largest city in Turkey, constituting the country's economic, cultural, and historical heart. With a population over 17 million, the city forms one of the largest urban agglomerations in Europe and is the second-largest city in the world by population within city limits. Istanbul is a transcontinental city, straddling the Bosphorus—one of the world's busiest waterways—in northwestern Turkey, between the Sea of Marmara and the Black Sea.

Founded on the Sarayburnu promontory around 660 BC as Byzantium, the city now known as Istanbul developed to become one of the most significant cities in history. For nearly sixteen centuries following its reestablishment as Constantinople in 330 AD, it served as the capital of four empires: the Roman Empire (330–395), the Byzantine Empire (395–1204 and 1261–1453), the Latin Empire (1204–1261), and the Ottoman Empire (1453–1922). It was instrumental in the advancement of Christianity during Roman and Byzantine times, before the Ottomans conquered the city in 1453 and transformed it into an Islamic stronghold and the seat of the last caliphate Although the Republic of Turkey established its capital in Ankara, palaces and imperial mosques still line Istanbul's hills as visible reminders of the city's previous central role.

Approximately 12 million foreign visitors arrived in Istanbul in 2012, two years after it was named a European Capital of Culture, making the city the world's fifth-most-popular tourist destination. The city's biggest draw remains its historic center, partially listed as a UNESCO World Heritage Site, but its cultural and entertainment hub can be found across the city's natural harbor, the Golden Horn, in the Beyoğlu district. Considered a global city, Istanbul is one of the fastest-growing metropolitan economies in the world.
