Istanbul is the only city in the world that straddles two continents — the Bosphorus Strait separating Europe from Asia bisects the city, making it simultaneously the largest city in Europe (by population, 15 million) and an Asian metropolis. For 1,500 years as Constantinople it was the capital of the Byzantine Empire and then the Ottoman Empire — and the civilizational weight of that history is visible on every hill: the Hagia Sophia (the greatest building of the ancient world, a mosque since 2020), the Blue Mosque (its six minarets visible from across the Golden Horn), Topkapi Palace (home of the Sultans for 400 years), and the Grand Bazaar (the world's oldest covered market, 4,000 shops). Istanbul today is also one of the most dynamic cities in the world — the food scene, the art galleries of Karaköy, the nightlife of Beyoğlu and the Bosphorus restaurant strip make it a destination that rewards multiple visits.
The Hagia Sophia (537 AD, Emperor Justinian — "I have surpassed you, Solomon" he reportedly said at its consecration, comparing it to the Temple in Jerusalem; for 1,000 years the largest cathedral in the world; converted to a mosque in 1453 by Mehmed the Conqueror; a museum 1934–2020; a mosque again from 2020) is the most extraordinary interior space in the world: the dome (31m diameter, 55m high) appears to float above the nave, supported by pendentives that are the greatest achievement of Byzantine engineering. Go at 8am to pray or simply experience it in near-silence.
🎫 Book tickets via GetYourGuideTopkapi Sarayi (begun 1459, the primary residence of the Ottoman sultans for almost 400 years, until 1856) is the most revealing palace in the world: the Harem (the private quarters of the sultan, his wives, concubines and children — 300 rooms, guided tours), the Imperial Treasury (the Topkapi Dagger, the Spoonmaker's Diamond, the Throne of Ahmed I in gold and emerald), and the sacred Relics section (including the mantle and sword of the Prophet Muhammad).
🎫 Book tickets via GetYourGuideThe Kapalı Çarşı (Grand Bazaar — founded 1455 by Mehmed the Conqueror, the oldest and largest covered market in the world with 61 covered streets, 4,000 shops and 250,000 visitors daily) sells carpets, gold jewellery, ceramics, spices, leather goods and everything imaginable. Do not feel pressured by merchants (a polite "hayır, teşekkürler" — no, thank you — is sufficient) and visit the Bedesten (the original inner market, finest carpets and antiques) for the most genuine experience.
🎫 Book tickets via GetYourGuideA meyhane (the traditional Turkish tavern, the word derived from the Persian for "place of wine" — though raki, the anise-flavoured spirit, is the drink of choice) with mezze (dozens of small dishes: cacık (yoghurt with cucumber and mint), tarama (fish roe), patlıcan salatası (smoky roasted aubergine), dolma (stuffed vine leaves), pastırma (air-dried cured beef), mücver (courgette fritters) and then grilled fish or lamb.

🎫 Book tickets via GetYourGuideThe Bosphorus (the 31km strait between the Black Sea and the Sea of Marmara, dividing Europe from Asia, 700m at its narrowest — all Black Sea shipping passes through here) is Istanbul's greatest experience: the public Şehir Hatları ferry (line 30 or round trip cruise, ₺200–400) passes the wooden yalı (Ottoman waterfront mansions), the Rumeli Hisarı fortress (1452, built in 3 months by Mehmed the Conqueror to blockade Constantinople), the two suspension bridges and the Black Sea mouth.
🎫 Book tickets via GetYourGuideDolmabahçe Sarayı (1856, commissioned by Sultan Abdülmecid I — 45,000 m², 285 rooms, 43 salons, 6 galleries, the world's largest chandeliers (the Bohemian crystal and Baccarat chandelier in the Ceremonial Hall weighs 4.5 tonnes)) replaced Topkapi as the Ottoman residence in the 19th century and served as Atatürk's last residence — he died in Room 71 at 9:05am on 10 November 1938; all clocks in the palace are stopped at that time.
🎫 Book tickets via GetYourGuideThe Galata Tower (1348, built by the Genoese colony of Galata — 67m, 9 floors, the tallest building in Constantinople for centuries) gives a 360° panorama of Istanbul: the domes and minarets of the old city, the Golden Horn, the Asian shore and the Bosphorus. The Karaköy neighbourhood (the harbour area below the tower) has become Istanbul's most creative district: coffee roasters, design shops, galleries and the Karaköy Güllüoğlu baklava shop (the finest baklava in Istanbul).
🎫 Book tickets via GetYourGuideIstiklal Caddesi (Independence Avenue — the 1.4km pedestrian boulevard of Beyoğlu, 3 million people pass through on a weekend day) and the side streets (Nevizade for meyhanes, Asmalımescit for wine bars, Cihangir for the bohemian café scene) give the most vibrant Istanbul nightlife experience. The nostalgic tram on Istiklal (the only surviving section of the original Constantinople tramway) still runs. End at a fish and raki bar at Kumbaracı 50.
🎫 Book tickets via GetYourGuideThe Sultanahmet Camii (Blue Mosque — 1616, Sultan Ahmed I, the only mosque in Istanbul with six minarets, competing with the mosque at Mecca before Ahmed built a seventh at Mecca — named for the 20,000 Iznik tiles in blue, white and green covering the interior) is the most beautiful mosque in Turkey. Closed to tourists during prayer times (5 times daily, ~30 min each) — arrive at 9:30am for the post-Fajr tourist opening. Remove shoes, women cover head.
🎫 Book tickets via GetYourGuideThe Mısır Çarşısı (Egyptian Bazaar / Spice Bazaar — 1664, built from the revenues of Egypt under Ottoman rule) is the finest covered spice market in the world: conical mounds of dried chilli, cumin, saffron, sumac and baharat (the Turkish spice blend), dried figs and apricots, Turkish delight (lokum) in 50 flavours, and the most pungent dried herbs in the eastern Mediterranean. The fish market outside (Mısır Çarşısı çevresi) is extraordinary on weekend mornings.
🎫 Book tickets via GetYourGuideThe Kadıköy ferry (₺15, 15 min from Eminönü) crosses to the Asian side of Istanbul — Kadıköy (the most bohemian neighbourhood in Istanbul, on the Anatolian shore) has the finest food market in the city (Kadıköy Çarşısı — fresh produce, cheese, olive stalls), the best coffee shops, the most atmospheric fish restaurants and the curious experience of standing in Asia looking back at the European Istanbul skyline across the water.
🎫 Book tickets via GetYourGuidePierre Loti Café (Eyüp Hill, reached by cable car from Eyüp Sultan Mosque — named after the French naval officer and novelist Pierre Loti who spent years in Istanbul and set several novels here) gives the finest sunset view of the Golden Horn: the minarets of the old city, the Fatih mosque and the Bosphorus bridge in silhouette. The Eyüp Sultan Mosque below (the holiest mosque in Istanbul, built over the tomb of Eyüp Ensari, companion of the Prophet) is an important pilgrimage site.
🎫 Book tickets via GetYourGuideBalık-ekmek (the iconic Istanbul street food — grilled mackerel, onion, tomato and lettuce in a half-loaf of bread, cooked on rocking boats moored at the Galata Bridge, ₺70) is the city's most democratic meal. The Galata Bridge (the 490m bridge over the Golden Horn, lined with fishermen casting lines day and night, each floor a tea garden) is the best people-watching spot in Istanbul. Finish with a tea at one of the bridge-level tea gardens and watch the boats pass.
