Istanbul: City of Two Continents

What is Istanbul?

Istanbul is the only city built across two continents. The Bosphorus runs through the middle of it, carrying ships between the Black Sea and the Mediterranean and separating the European districts from the Asian ones. The Turkish Statistical Institute puts the population of the province at just under sixteen million, which makes it the largest city in Europe, and the ferries crossing between the two sides are ordinary commuter transport rather than a tourist attraction.

It has been the capital of three empires. The Greek colonists who founded Byzantium in the seventh century BC chose the spot for its natural harbour, the Golden Horn. Constantine made it the capital of the Roman Empire in 330 AD, and for the next eleven centuries it was Constantinople, the seat of Byzantium. The Ottomans took it in 1453 and ruled from here until 1922. When the Republic was declared in 1923 the capital moved to Ankara, and Istanbul lost its administrative role but kept everything else.

That layering is what makes the city difficult to summarise. A sixth-century church, a fifteenth-century mosque and a nineteenth-century apartment block regularly share the same street corner. The historic peninsula holds the monuments most visitors come for, and has been on the UNESCO World Heritage List since 1985, but the city lives in Beyoglu, Kadikoy, Besiktas and a hundred neighbourhoods that appear in no itinerary.

How do you get to Istanbul?

Two airports serve the city, and which one you land at matters more than most travellers expect. Istanbul Airport is on the European side, north-west of the centre, and handles most long-haul and flag-carrier traffic. The M11 metro runs from the terminal to Gayrettepe, where you change onto the M2 for Taksim or continue towards the old city. Havaist coaches run to Taksim, Beyazit and Kadikoy.

Sabiha Gokcen Airport is on the Asian side and serves most low-cost and regional flights. The M4 metro connects it to Kadikoy, from where ferries cross to Eminonu and Karakoy. Crossing the city between the two airports takes well over two hours in traffic, so treat a connection that involves both as two separate journeys.

Trains from Europe terminate at Halkali on the western edge, with a suburban rail link into the centre. Long-distance buses arrive at Esenler otogar, which is functional rather than pleasant. Cruise ships dock at Galataport in Karakoy, which puts passengers within walking distance of Galata Tower and one tram stop from the old city.

What should you pack for Istanbul?

Shoes first. The old city is hilly, the pavements are uneven, and a full day of sightseeing easily passes fifteen thousand steps. Whatever you bring, you will be walking on cobbles and marble in it.

Mosques are working places of worship and expect covered shoulders and knees from everyone, with a headscarf for women. Most major mosques lend scarves at the door, but carrying a light one saves queuing for it. Shoes come off before entering, so socks and footwear you can slip out of are practical.

Layers matter more than heavy coats. The city sits between the Black Sea and the Marmara and the wind changes what the temperature feels like within an hour. Summer is humid rather than dry, so light fabrics work better than shorts alone. Winter is damp and windy rather than deeply cold, and a waterproof shell is more useful than a thick jacket. An umbrella is worth having from November to April.

Where should you stay in Istanbul?

Sultanahmet puts you inside the monument district. Hagia Sophia, the Blue Mosque, Topkapi and the Basilica Cistern are within a few minutes of each other, which saves a great deal of transit time on a short trip. The trade-off is that the neighbourhood empties in the evening and the restaurants aimed at visitors are not where locals eat.

Karakoy, Galata and Cihangir sit across the Golden Horn and are the opposite: better food, better bars, more of a living neighbourhood, and a tram or a fifteen-minute walk from the old city. This is where most repeat visitors stay.

Besiktas and Ortakoy face the Bosphorus and suit travellers who want water views and a quieter base with good ferry connections. Kadikoy, on the Asian side, has the best market streets and the liveliest evenings, and is twenty minutes by ferry from the old city. Staying there costs less and shows you a version of Istanbul most visitors never see.

Taksim is central and well connected but noisy, and the streets immediately around it are not the city at its best.

What type of climate does Istanbul have

Istanbul has a transitional climate that borrows from the Mediterranean and the Black Sea. Summers are hot and humid, with July and August routinely in the low thirties and little rain. Winters are cool and wet rather than freezing, hovering a few degrees above zero at their coldest, with occasional snow that closes the city for a day or two and then melts.

The wind is the variable that catches people out. The northerly poyraz drops the temperature sharply and whips up the Bosphorus; the southerly lodos brings warm, damp air and sometimes suspends ferry services. Rain is spread across the year but concentrated between November and March.

When is the best time to visit Istanbul

April to early June and September to October are the two windows where the weather, the daylight and the crowds all line up. Days are warm without being oppressive, the evenings are comfortable enough to eat outside, and the queues at the major sights are shorter than in high summer.

April has one particular draw: the tulip season, when the parks at Emirgan and Gulhane are planted out in the hundreds of thousands. It is the flower Istanbul sent to the Netherlands rather than the other way round.

July and August are hot, humid and busy, and the historic peninsula is exhausting in the middle of the day. If you come then, do your sightseeing early and spend the afternoon on a ferry.

November to March is grey, damp and much quieter. Museums are calm, hotel rates drop, and the city has a particular atmosphere in the rain that photographs well. Bring a coat and accept that some days will be wet.

Ramadan is worth knowing about either way. The mosques are at their most atmospheric, the evenings are festive, and the courtyards fill for the breaking of the fast, but daytime restaurant hours in conservative districts can change.

What is the history of Istanbul?

The city begins with a harbour. Greek settlers from Megara founded Byzantium on the promontory where the Golden Horn meets the Bosphorus around 660 BC, choosing a site that controlled the only sea route between the Mediterranean and the Black Sea. That geography decided everything that followed.

In 330 AD Constantine refounded it as the eastern capital of the Roman Empire. When the western half collapsed in the fifth century, Constantinople carried on as Rome, and did so for another thousand years. Justinian rebuilt the centre after the Nika riots of 532 and raised Hagia Sophia, whose dome was the largest in the world for nearly a millennium. The Theodosian land walls, finished in the fifth century, held off besieging armies for a thousand years.

The city was sacked once by its own side: the Fourth Crusade turned on it in 1204 and stripped it of relics and bronze that ended up in Venice and elsewhere. Byzantium recovered the city in 1261 but never recovered its wealth.

On 29 May 1453 Mehmed II took Constantinople after a siege of fifty-three days, using cannon large enough to need teams of oxen to move. He was twenty-one. The city became the Ottoman capital, and over the following century Sinan, the imperial architect, gave it the skyline it still has: Suleymaniye, Sehzade, Rustem Pasha and dozens more.

The nineteenth century brought European-style palaces along the Bosphorus, the first underground railway on the continent after London, and the terminus of the Orient Express. Occupation followed the First World War, the Republic followed in 1923, and the capital moved to Ankara. Istanbul spent the twentieth century growing from under a million people to more than fifteen million.

What is Istanbul famous for?

Hagia Sophia held the record for the largest interior dome in the world for close to a thousand years, and the engineering that supports it was not matched until the Renaissance.

The Tunel funicular, opened in 1875 between Karakoy and Beyoglu, is among the oldest underground urban railways anywhere and still runs the same short climb.

The Grand Bazaar, begun in 1461, is one of the oldest and largest covered markets in the world, with more than sixty streets under one roof.

The Marmaray tunnel, opened in 2013, runs beneath the Bosphorus and is one of the deepest immersed tube tunnels ever built. Construction was repeatedly delayed by what the diggers found. The excavation at Yenikapi uncovered the lost Theodosian harbour, thirty-seven Byzantine shipwrecks dating from the fifth to the eleventh century — the largest collection of medieval ships found anywhere — and Neolithic burials that pushed the evidence of settlement here back more than eight thousand years. The finds are held by the Istanbul Archaeological Museums.

Istanbul is also the only city in the world on two continents, and the only one that has been the capital of both a Christian and an Islamic empire.

What are the historical places of Istanbul?

Hagia Sophia. Built in 537 as the great church of Byzantium, converted to a mosque in 1453, made a museum in 1935 and returned to use as a mosque in 2020. The Byzantine mosaics and the Ottoman calligraphic roundels share the same interior, which is the whole point of the building.

The Blue Mosque. Sultan Ahmed I built it between 1609 and 1616 directly facing Hagia Sophia, a deliberate architectural argument. The name comes from the twenty thousand Iznik tiles lining the upper interior. It has six minarets, which caused a scandal at the time because Mecca had the same number.

Topkapi Palace. The Ottoman court ran from here for almost four centuries. It is not one building but a series of courtyards, each more restricted than the last, ending in the Harem and the treasury. The layout tells you more about how the empire worked than any single room.

The Basilica Cistern. A sixth-century underground reservoir held up by 336 columns collected from older buildings, with two carved Medusa heads used as column bases in the far corner.

Suleymaniye Mosque. Sinan’s masterpiece from the 1550s, on the third hill with the best free view in the old city. Quieter than the Blue Mosque and, to many eyes, the finer building.

Chora Church. Out by the land walls, and holding the most complete cycle of late Byzantine mosaics and frescoes anywhere. Worth the journey.

The Theodosian walls. Six kilometres of fifth-century fortification running from the Marmara to the Golden Horn, in varying states of ruin and restoration, and walkable in sections.

Galata Tower. Built by the Genoese in 1348 as part of their walled colony across the Golden Horn, and still the landmark of that skyline.

Dolmabahce Palace. The nineteenth-century Ottoman answer to European palaces, all crystal and gilt on the Bosphorus shore. Ataturk died here in 1938, and the palace clocks are stopped at the hour.

Who are the most famous people in the history of Istanbul

Constantine the Great refounded the city as the Roman capital in 330 AD and gave it his name for the next sixteen centuries.

Justinian I rebuilt the centre after the Nika riots and commissioned Hagia Sophia, along with the cisterns and much of the infrastructure beneath the old city.

Mehmed II took the city in 1453 at twenty-one and set about repopulating it, inviting back Greeks, Armenians and Jews and building the first covered market.

Mimar Sinan served three sultans as chief architect and built or supervised hundreds of structures across the empire. Suleymaniye and the Rustem Pasha Mosque are his, and so is the water system that supplied them.

Suleiman the Magnificent presided over the empire at its height in the sixteenth century, when the city was the largest in Europe.

Orhan Pamuk won the Nobel Prize in Literature in 2006, and his memoir of the city gave the word huzun, a particular civic melancholy, to readers outside Turkey. His Museum of Innocence in Cukurcuma is a novel turned into a building.

What are the best things to do in Istanbul?

1. Walk into Hagia Sophia and look up before you look at anything else.

2. Cross the Bosphorus on a public ferry at least once. The commuter boats from Eminonu to Kadikoy or Uskudar cost a transport fare and give you the same skyline as the cruises.

3. Spend a morning in Topkapi Palace, and pay the extra for the Harem, which is the part people regret skipping.

4. Get lost in the Grand Bazaar on purpose, then walk downhill through Mahmutpasa to the Spice Bazaar.

5. Climb to the Suleymaniye terrace at sunset for the view over the Golden Horn.

6. Eat breakfast properly. A Turkish kahvalti is a two-hour table of small plates, not a pastry on the way somewhere.

7. Take the ferry to Kadikoy and walk the market streets around Serasker Caddesi.

8. Visit a hamam. The historic ones in the old city are architecture as much as bathing.

9. Go out to Chora for the Byzantine mosaics, and walk a stretch of the land walls while you are there.

10. Ride the Tunel, the 1875 funicular, then walk down Istiklal Caddesi.

11. Spend an afternoon in Balat and Fener, where the painted houses, the Greek Orthodox patriarchate and the antique shops are.

12. Drink tea on the upper deck of the Galata Bridge while the fishermen work the rail above you.

13. Take a boat to the Princes’ Islands, where cars are banned and the pace drops immediately.

14. See the Basilica Cistern, then one of the smaller cisterns nearby for contrast.

15. Watch the city from the water at dusk, when the minarets light up and the ferries start their evening runs.

What are the best places to visit in Istanbul?

The historic peninsula holds Hagia Sophia, the Blue Mosque, Topkapi, the Hippodrome, the cisterns and the bazaars, all within walking distance. Two days here is not too much.

Galata and Beyoglu are the nineteenth-century city: the tower, Istiklal Caddesi, the arcades and passages off it, Cukurcuma for antiques, Cihangir for cafes.

The Bosphorus villages run north on both shores. Ortakoy and Bebek on the European side, Kuzguncuk and Cengelkoy on the Asian, each with a waterfront and a very different atmosphere from the centre.

Kadikoy and Moda, across the water, are where Istanbul eats and drinks without an audience.

Balat and Fener, on the Golden Horn, are the old Jewish and Greek quarters, steep and colourful and increasingly photographed.

Eyup, further up the Horn, has the mosque complex and the cable car to Pierre Loti hill.

The Princes’ Islands are ninety minutes out by ferry: pine woods, wooden mansions, no cars.

Frequently asked questions about Istanbul

The best Istanbul Tours

Istanbul rewards a mix of guided and unguided time. The monuments of the old city are dense with history that is hard to read from the stones alone, and a guide who knows the Byzantine and Ottoman layers changes what you see in Hagia Sophia or Topkapi. The neighbourhoods are the opposite: Balat, Kadikoy and the Bosphorus villages are better walked without a schedule.

The tours people get the most out of are usually the Bosphorus cruise, a food walk on the Asian side, a guided morning in the historic peninsula, and a day trip to the Princes’ Islands. The Golden Horn is the quieter alternative on the water, running past Balat, Fener and Eyup rather than the palaces. A hamam visit is worth booking rather than turning up for, because the historic baths fill quickly, and the Cistern of Theodosius is the calm counterpart to the queue at the Basilica Cistern.

Where should you visit in Istanbul in winter?

Winter suits the indoor city. The mosques and museums are at their emptiest, and Hagia Sophia without a queue is a different experience. The Archaeological Museums, the Museum of Turkish and Islamic Arts, the Pera Museum and Istanbul Modern all fill a wet afternoon.

The bathhouses make more sense in January than in July, and the historic hamams are properly warm. Tea houses and the nargile courtyards around Corlulu Ali Pasa are built for this weather.

The ferries still run, and the Bosphorus in winter light, with the mist sitting on the water, is worth a crossing in a coat. If it snows, the old city under snow is the photograph everyone wants, and it usually lasts a day.

Where should you visit in Istanbul in summer?

Summer moves the city outdoors and towards the water. The Princes’ Islands come into their own, with swimming spots and bicycles and the ferry breeze on the way out.

The Bosphorus villages are where locals spend summer evenings: Bebek, Arnavutkoy and Ortakoy on the European shore, Cengelkoy and Kuzguncuk on the Asian. The waterfront tea gardens run late.

Rooftop terraces open across Galata and Karakoy, and the parks at Gulhane, Yildiz and Emirgan give shade in the middle of the day. Do the monuments in the early morning and leave the afternoon for the sea.

What are the best beaches in Istanbul?

Istanbul is a city on the water rather than a beach destination, but there is swimming within reach.

The Princes’ Islands have the closest proper swimming, with clubs and bays on Buyukada and Heybeliada reached by ferry from Kabatas, Eminonu or Kadikoy.

The Black Sea coast north of the city, around Kilyos on the European side and Sile on the Asian, has open sand and real surf. The currents there are strong and the swimming is not always safe, so pay attention to flags and lifeguards.

Closer in, Florya and Caddebostan have city beaches that are convenient rather than beautiful. Do not swim in the Bosphorus itself; the current is fast and the shipping traffic is constant.

What is nightlife like in Istanbul?

The city has several distinct evening scenes rather than one.

Beyoglu, around Asmalimescit and the streets off Istiklal, is the densest: meyhanes with raki and meze, live music bars, and places that stay open very late.

Karakoy has the newer bars and rooftops, with views back to the old city.

Kadikoy, on the Asian side, is where a younger crowd drinks, around Kadife Sokak and the bars off the market. Cheaper and less polished than Beyoglu.

Ortakoy and Bebek run to waterfront clubs and expensive terraces along the Bosphorus.

A meyhane evening is the tradition worth trying: small plates arriving in waves, raki cut with water, and no hurry about any of it. Live fasil music is common and the evening tends to end much later than planned.

What is the traditional food of Istanbul?

Breakfast is the meal Istanbul does best. Cheeses, olives, tomatoes, cucumbers, honey with clotted cream, jams, eggs cooked in butter, and endless tea, spread across a table for as long as you want to sit there.

Balik ekmek, grilled fish in bread, is sold from boats and stalls at Eminonu and is the city’s own street food.

Midye dolma, mussels stuffed with spiced rice and eaten with lemon, is sold from trays on every busy corner after dark.

Kokorec divides visitors: seasoned grilled offal chopped into bread, and a late-night institution.

Iskender is doner over bread with tomato sauce and melted butter. Lahmacun and pide are the flatbreads. Manti, tiny dumplings under garlic yoghurt, is worth seeking out.

Meze covers the whole meyhane table: aubergine, broad beans, stuffed vine leaves, octopus salad, whatever the kitchen made that morning.

For sweets, baklava, kunefe with its stretched cheese under shredded pastry, and dondurma, the stretchy mastic ice cream from Maras.

Where are the best restaurants in Istanbul?

The useful distinction is by type rather than by name, because the specific places change.

Meyhane for the long evening of meze and raki, mostly in Beyoglu, Kumkapi and Kadikoy.

Ocakbasi for grilled meat cooked over coals in front of you, the Istanbul kebab houses.

Esnaf lokantasi for the everyday: trays of home-style stews and vegetables in olive oil, chosen by pointing, eaten at lunchtime with the people who work nearby. This is the best value eating in the city.

Balik restoran for fish, at their best in the Bosphorus villages and on the Kumkapi and Karakoy waterfronts.

Kahvalti salonu for breakfast, particularly in Besiktas, Moda and Cihangir.

A practical rule: in Sultanahmet, walk two streets away from the monuments before you sit down. On the Asian side you can eat almost anywhere.

What should you buy in Istanbul?

Spices, tea and dried fruit from the Spice Bazaar and the streets around it. Buy whole spices rather than ground.

Turkish delight and baklava from a specialist rather than a stall, and ask to taste first.

Coffee, freshly ground, from one of the old grinders near the Spice Bazaar.

Ceramics and Iznik-style tiles, with the caveat that hand-painted and transfer-printed look similar at a glance and cost very different amounts. Ask which it is.

Carpets and kilims, which reward research before you shop. Ask about material, knot density and origin, and expect to bargain.

Copper and brassware from the workshops in the Grand Bazaar’s inner streets, and evil eye glass, which is everywhere and genuinely local.

Textiles: peshtemal towels from the hamam supply shops, and soap from Bursa and Antakya.

Haggling is expected in the bazaars and in carpet, leather and jewellery shops. It is not expected in food shops, supermarkets or fixed-price stores, and pushing there is simply awkward.
