Istanbul

Hagia Sophia, completed in 537 under Byzantine emperor Justinian, was for nearly a thousand years the largest cathedral in the Christian world before becoming a mosque in 1453 upon the Ottoman conquest, then a museum in 1935, and a mosque again since 2020. Its massive 55-meter-high dome, a remarkable feat of engineering for its time, appears to float above the immense nave thanks to a ring of windows at its base. The interior uniquely and fascinatingly blends Byzantine mosaics depicting Christ and the Virgin Mary with large Ottoman calligraphic medallions bearing the names of Allah, Muhammad, and the early caliphs. Entry to the main mosque area is now free, with visiting hours organized around the five daily prayers. Modest, covering clothing is required, and a headscarf is provided to women at the entrance if needed.

The Blue Mosque, or Sultan Ahmed Mosque, was built between 1609 and 1616 on the orders of Sultan Ahmed I to rival the splendor of Hagia Sophia just across from it. It takes its nickname from the more than 20,000 blue Iznik ceramic tiles lining the interior of its walls and domes, creating a luminous, soothing atmosphere enhanced by 260 windows. Its six minarets, an exceptional number that sparked religious controversy at the time (only Mecca had as many), make it an instant visual landmark on the Sultanahmet skyline. The mosque remains an active place of worship, closed to non-Muslim visitors for about 90 minutes during each of the five daily prayers. Entry, which is free, is through a dedicated tourist queue on the west side, with shoes off and modest clothing required.

The Basilica Cistern, built in 532 under Emperor Justinian, is the largest of the hundreds of underground reservoirs that supplied Constantinople with water since Byzantine antiquity. A vaulted ceiling rests on 336 marble columns, 9 meters tall, salvaged from ancient Greek and Roman temples and arranged in 12 rows within a dim space enhanced by soft lighting and ambient music. Two columns rest on upturned Medusa heads, one sideways and one upside down, whose exact origin is still debated by historians. Long forgotten before its 16th-century rediscovery by a traveler intrigued to see locals fishing through their basement floors, the cistern has since inspired novels and films, including a James Bond movie. An elevated walkway lets you tour the whole space in 30 to 45 minutes, in a truly one-of-a-kind atmosphere.

Topkapi Palace was the main residence of the Ottoman sultans and the center of imperial power for nearly 400 years, from 1465 to 1856, before the court moved to Dolmabahçe Palace. Organized around four successive courtyards, each more private than the last, the complex today houses a museum displaying the imperial treasury, including the famous emerald-encrusted Topkapi Dagger and the Spoonmaker's Diamond, one of the largest cut diamonds in the world. The harem, the palace's most intimate section where the sultan's wives, concubines, and mother lived, requires a separate ticket and reveals rooms lavishly decorated with Iznik ceramics. The gardens and terraces also offer one of the finest views combining the Golden Horn, the Bosphorus, and the Sea of Marmara in a single panorama. Allow at least 2.5 to 3 hours for the full visit, harem included.

Istanbul's Grand Bazaar, opened in 1461 under the reign of Mehmed II, is one of the largest and oldest covered markets in the world, a true maze of 61 vaulted, colorful streets housing more than 4,000 shops. You'll find everything: handmade carpets, Iznik ceramics, colored glass mosaic lamps, gold and silver jewelry, spices, textiles, and souvenirs of every kind, arranged according to old craft guilds still traceable in the bazaar's layout. Haggling here isn't just accepted, it's expected, with listed prices mostly serving as a starting point for negotiation. Beyond the shopping, the Ottoman architecture itself is worth admiring, with painted ceilings and historic doors still standing after centuries. Plan to get deliberately lost in the quieter lanes, often more authentic than the main aisles packed with tourists.

T1 tram, Beyazıt-Kapalıçarşı stop - direct entrance onto the square.

The Egyptian Bazaar, or Spice Bazaar, was built in 1664 to fund the upkeep of the nearby New Mosque, of which it still remains an annex. Much more compact than the Grand Bazaar but just as captivating, its 85 L-shaped stalls offer colorful mountains of spices, teas, dried fruit, medicinal herbs, and of course lokum in every imaginable flavor, from pistachio to rose. Its name historically comes from the spices arriving from Egypt that passed through here in the 17th century, making the site a trading crossroads between Europe and the East. Outside, the lively Eminönü district extends the experience with street vendors selling simit (sesame-crusted bread rings), freshly grilled fish, and tea served in small tulip glasses. It's an essential stop for authentic edible souvenirs.

T1 tram, Eminönü stop - 2 min walk, near the Galata Bridge.

Süleymaniye Mosque, built between 1550 and 1557 by the great Ottoman architect Mimar Sinan for Suleiman the Magnificent, is universally regarded as the pinnacle of classical Ottoman architecture. Perched on one of Istanbul's seven hills, it overlooks the Golden Horn with a central dome 53 meters high, skillfully balanced by half-domes, a technical feat that would influence Ottoman architecture for centuries. Unlike the often-crowded Sultanahmet sites, it remains remarkably peaceful and is mostly visited by local worshippers rather than tourists. The surrounding complex (külliye) originally included a Quranic school, a hospital, a hammam, and a soup kitchen for the poor, some of whose buildings now house traditional restaurants and cafes. The gardens surrounding the mosque offer one of the finest free viewpoints over the Golden Horn and the Bosphorus, especially lovely at sunset.

Galata Tower, built in 1348 by the Genoese as the highest point of their trading colony's fortifications, now overlooks the lively Galata district at 66.9 meters tall. According to local legend, it was from its summit that Hezârfen Ahmed Çelebi supposedly leapt in the 17th century with artificial wings to glide across the Bosphorus, becoming one of the very first aviators in history. Its circular observation deck today offers an absolutely spectacular 360-degree view over the Golden Horn, the Bosphorus, Sultanahmet, and the surrounding hills, especially beautiful at sunset. The Galata district around it, with its steep lanes lined with cafes, art galleries, and design shops, has become one of Istanbul's trendiest neighborhoods in recent years.

Dolmabahçe Palace, built between 1843 and 1856 on the orders of Sultan Abdülmecid I, marks the definitive break from Topkapi's traditional Ottoman style in favor of resolutely European opulence, blending Baroque, Rococo, and Neoclassical styles. Its 285 rooms and 46 halls stretch along 600 meters of facade on the Bosphorus, decorated with 14 tons of gold leaf and the largest Bohemian crystal chandelier, a gift from Queen Victoria, hanging in the ceremonial hall. It was in this palace that Mustafa Kemal Atatürk, founder of the Turkish Republic, spent his final years and died on November 10, 1938, at precisely 9:05 am; every clock in the palace has remained frozen at that hour ever since in tribute. The mandatory guided tour, split between the Selamlık apartments (the official section) and the Harem, lasts about 1 to 1.5 hours and showcases this pinnacle of late Ottoman imperial splendor.

A cruise on the Bosphorus strait, the strategic waterway separating Europe from Asia and linking the Black Sea to the Sea of Marmara, is one of the most memorable ways to see Istanbul from a different angle. Tourist and public ferries hug the shores lined with yalıs (elegant Ottoman wooden mansions), medieval fortresses like Rumeli Hisarı, and lavish palaces such as Dolmabahçe and Beylerbeyi, before passing beneath the impressive suspension bridges linking the two continents. Public ferries (Şehir Hatları) run a full route up to the picturesque village of Anadolu Kavağı for a modest fare, while shorter private sunset cruises offer a more intimate atmosphere, sometimes with dinner on board. It's also the ideal chance to take in the full Sultanahmet skyline from the water, domes and minarets lined up along the Golden Horn.

Ferries from Eminönü or Kabataş - several daily departures, very affordable public fares.
