Istanbul

Istanbul is Turkey's largest city and a transcontinental metropolis spanning Europe and Asia along the Bosphorus. Once known as Byzantium and later Constantinople, it served as the capital of the Roman, Byzantine and Ottoman empires, and today blends a deep historic core with fast-growing modern districts.

The historic peninsula holds landmarks such as Hagia Sophia, the Blue Mosque, Topkapı Palace and the Basilica Cistern, while the Grand Bazaar and the Spice Bazaar continue centuries of trade. Along the Bosphorus, ferries pass waterfront palaces, fortresses and hillside neighbourhoods that connect the Black Sea and the Sea of Marmara.

Neighbourhoods differ sharply across the city. Sultanahmet concentrates major monuments, Beyoğlu and Galata offer nightlife and 19th-century architecture, Karaköy and Kadıköy are known for cafés and food culture, and districts such as Nişantaşı, Bebek and Beşiktaş feature upscale shopping and dining. Museums including Istanbul Modern, the Istanbul Archaeology Museums and the Pera Museum add to the cultural mix.

Istanbul is also Turkey's economic and financial centre, with strong roles in trade, logistics, conferences, exhibitions and a growing technology and startup scene. Its food culture ranges from street food and meyhanes to seafood, Anatolian dishes and Ottoman-influenced cuisine, supported by a busy calendar of concerts, festivals and cultural events.

For leisure and business travellers alike, Istanbul combines historic sightseeing, cultural depth, modern amenities and extensive international flight connections, making it one of the world's most distinctive urban destinations.
