Istanbul

Why go

Two empires on one peninsula — Byzantine and Ottoman capitals occupy the same ground, often the same buildings. A working strait — the Bosphorus is commuter infrastructure, and the cheapest sightseeing in Europe is a ferry ticket. A food city of migration — Anatolian, Greek, Armenian, Kurdish and Black Sea kitchens within a few streets. Scale with a village texture — sixteen million people, and neighbourhoods that still function as villages.

The character

Constantine moved the Roman capital here in 330 because the peninsula is defensible on three sides and controls the only sea route between the Black Sea and the Mediterranean. Every subsequent chapter follows from that geography. The Byzantines built walls that held for a thousand years; mehmed II took the city in 1453 and immediately converted rather than destroyed — Hagia Sophia became a mosque, the Ottoman architects studied its dome and spent a century answering it, and Sinan's mosques are the reply.

What makes Istanbul different from other imperial cities is that nothing was ever fully replaced. The Basilica Cistern still holds water under a shopping street. Greek and Armenian churches operate in Fener and Kumkapı. The Grand Bazaar's plan follows fifteenth-century trade guilds and still sorts by them. And the Bosphorus keeps the whole arrangement in motion: tankers, ferries, fishing boats and the daily migration of half the population between continents. This is a city where the ordinary act of commuting crosses from Europe to Asia, and the residents find that entirely unremarkable — which is the correct attitude to borrow.

Places of character

Süleymaniye Mosque — Sinan's masterpiece of 1557, with a terrace over the Golden Horn and a soup kitchen still in the complex. Chora Church — fourteenth-century mosaics and frescoes, the finest late Byzantine work anywhere, in a quiet outer district. Kadıköy market, Asian side — where Istanbul shops and eats without an audience; the fish, pickle and cheese shops are the point. Balat and Fener — the old Jewish and Greek quarters, steep streets of painted houses and the Ecumenical Patriarchate. A Bosphorus ferry to Anadolu Kavağı — ninety minutes each way, past palaces and wooden yalı houses, for the price of a bus. Süleymaniye's back streets at prayer time — carpenters, bookbinders and tea houses, unchanged in trade for generations.

The way to do it

Divide days by continent, not by monument. Use the ferries constantly — they are the correct way to understand the city's shape. Eat breakfast late and long, as Istanbullus do, and take at least one meal on the Asian side. Book Hagia Sophia and Topkapı for opening time and treat the afternoons as walking over queueing.

One perfect day

Simit and tea at a ferry terminal before eight, then the boat to Kadıköy while the light is still low on the water. Breakfast at a market table with cheese, olives, eggs and endless tea. Back across for Süleymaniye at midday, when the courtyard is cool and the terrace has the whole Golden Horn. Walk down through the guild streets to the Spice Bazaar, then take a taxi out to Chora for the mosaics with almost nobody in the room. Late afternoon on a ferry up the Bosphorus as the yalıs light up. Dinner in a meyhane in Beyoğlu — meze brought to the table on a tray, rakı with water and ice, and the fish course arriving whenever it arrives.

Grand hotels

Pera Palace — built in 1892 for Orient Express passengers, with Agatha Christie's room preserved and the lift Europe's oldest in continuous use. Çırağan Palace — an Ottoman sultan's palace on the Bosphorus, its waterfront terrace the best seat on the strait.

When to go

Best expression: April to early June, when the tulips are out and the ferries are comfortable on deck. Consider: late September and October, warm water, clear light and the city back from summer. Avoid if possible: August heat and humidity, and the first days of Ramadan Bayram, when everything is either shut or full.
