What is Istanbul Best Known For?

If you are planning your first trip and trying to picture the place, the short version is easy to give. Istanbul is best known for sitting on two continents, for a skyline crowded with imperial mosques and Byzantine domes, for the Bosphorus that splits the city in half, for one of the oldest covered markets on earth, and for food that quietly ruins your appetite for anywhere else. It was the capital of two empires, and you feel that weight everywhere you walk.

That is the headline. The honest answer takes a little longer, because no single thing carries this city. What follows is what I would actually tell a friend who asked me the same question over a glass of tea.

The city that lives on two continents

Start with the thing nowhere else can claim. Istanbul straddles Europe and Asia, and the Bosphorus is the strait that runs between them, connecting the Black Sea to the Sea of Marmara. People here cross from one continent to the other on a ferry that costs about the same as a city bus, and they do it without a second thought, coffee in hand, gulls trailing the boat for simit crumbs.

That geography is the reason for everything else. The strait made the city a hinge between trade routes, which made it worth conquering, which is why so many empires built here. Spend an afternoon riding the public ferries between the European and Asian sides and you will understand the place better than any museum can teach you. The European side around Sultanahmet holds most of the famous monuments, while the Asian side, anchored by Kadıköy, is where locals actually eat, drink and hang out away from the crowds.

History you can reach out and touch

Istanbul has been Byzantium, then Constantinople, then the seat of the Ottoman sultans, and the layers have never been scrubbed away. This is the big reason people come, and it deserves the top billing.

The single most famous building is Hagia Sophia. It was finished in 537 AD as a Byzantine cathedral, became a mosque after the Ottoman conquest in 1453, served as a museum for most of the 20th century, and is now a working mosque again. The ground floor is reserved for worship, and tourists visit the upper gallery to see the gold Byzantine mosaics. At the time of writing the foreign visitor ticket for that gallery is around 25 euros, and it closes to sightseers during the five daily prayer times, so check before you queue.

Across the square stands the Blue Mosque, properly the Sultan Ahmed Mosque, the one with six minarets and the cascade of grey domes that gives it the postcard silhouette. A few minutes’ walk away you can drop underground into the Basilica Cistern, a sixth-century Byzantine reservoir held up by 336 columns, two of them resting on carved Medusa heads nobody has fully explained. Then there is Topkapı Palace, home to the Ottoman sultans for nearly four centuries, with a treasury, a harem and terraces that look straight down the Bosphorus.

My honest advice: do not try to cram all of these into one rushed morning. Sultanahmet rewards a slow pace. Pick two big sites a day, sit down for tea in between, and let the place breathe.

The mosques and the call to prayer

Even people with no interest in religion remember the soundtrack. Five times a day the call to prayer rises from hundreds of minarets across the city, the voices overlapping from one neighbourhood to the next. At sunset, heard from a rooftop with the domes turning gold, it is one of those moments that explains why Istanbul stays with you.

Beyond the famous two, the Süleymaniye Mosque is the one I send people to first. It sits high on a hill, it is the masterpiece of Mimar Sinan, the greatest Ottoman architect, and the terrace beside it gives you a free panorama over the Golden Horn that beats most paid viewpoints. The pretty little Ortaköy Mosque right on the water, framed by the first Bosphorus bridge, is the postcard everyone photographs.

The Grand Bazaar and the art of the haggle

Istanbul is famous for shopping, and the Grand Bazaar is the headline act. It dates to the 1450s, just after the conquest, and today it sprawls across roughly 60 covered streets with around 4,000 shops selling carpets, lamps, ceramics, gold, leather and a great deal of cheerful nonsense. It is open Monday to Saturday, roughly 9am to 7pm, and it is closed all day Sunday, which trips up a lot of visitors, so plan around that.

Two things worth knowing. First, the first price is never the real price, so haggling is expected and the vendor will respect you more for it. Second, walk ten minutes northeast to the Spice Bazaar near Eminönü for the smell of saffron and dried fruit, and to the quiet streets around it where actual locals buy their textiles for half the bazaar price.

A food city, full stop

Ask anyone who has been, and the food comes up within a minute. Istanbul runs on it, and the best of it is cheap and eaten standing up. You can read the whole story in our guide to Istanbul cuisine, but here is the short list.

Start with breakfast, because a Turkish breakfast is a proper event: cheeses, olives, tomatoes, eggs, jams, fresh bread and endless tea, the kind of spread that kills any plan to do much before noon. Then there is the street food. A simit, the sesame-crusted ring sold from every red cart, runs about 15 to 20 lira and is the cheapest good thing you will eat all day. Balık ekmek, a grilled fish sandwich eaten by the Galata Bridge, is the classic waterfront snack, though at the tourist-heavy Eminönü docks expect to pay a steep premium over a back-street spot. Round it off with baklava and a tiny cup of strong Turkish coffee, thick enough to stand a spoon in. If you only do one food thing here, make it a long, lazy breakfast and let the rest follow.

The Bosphorus, the bridges and the islands

The water is not just a backdrop, it is the main event for a lot of visitors, and rightly so. A Bosphorus cruise takes you past wooden waterfront mansions, Ottoman fortresses, the palaces and the two great suspension bridges linking the continents. You can do it cheaply on a public ferry or properly on a private boat. For a calmer, more flexible version away from the packed tour boats, a private Bosphorus yacht tour with Su Yatçılık lets you set your own pace and swim off the back if the weather is kind.

Keep going south and you reach the Princes’ Islands, a cluster of car-free islands in the Sea of Marmara where you get around on foot, bike or electric cart. They make one of the easiest day trips out of the city when you want pine trees, sea air and a slower rhythm.

So, what is Istanbul best known for?

Pulling it together: Istanbul is best known for being the city on two continents, for its imperial history written into Hagia Sophia and the great mosques, for the Bosphorus and the call to prayer over the rooftops, for the Grand Bazaar, and for food that turns a short trip into a habit. Those are the headlines.

But the real reason people keep coming back is harder to put on a list. It is the cats asleep on ancient marble, the tea glasses on every corner, the ferry horn at dusk, the way old and new sit on top of each other without apology.
