Two continents, three empires and one strait that everything else is arranged around. The old capital rewards a plan: the great monuments sit within a twenty-minute walk of each other in Fatih, and almost everything else is a ferry ride away.

Hagia Irene is the Byzantine church that was never made into a mosque, and it is the reason it still looks like a Byzantine church inside.
The Galata Mevlevihanesi is the oldest Mevlevi dervish lodge in Istanbul, established in 1491 during the reign of Bayezid II on land that had belonged to İskender Pasha, a prominent governor of the period.
Tekfur Sarayı is the last Byzantine palace in Istanbul still standing to its full height, and it survives because it was never important enough to be worth demolishing.
Şerefiye Sarnıcı is a Roman water tank that spent most of the last three centuries with a building sitting on top of it.
Kucuksu is a kasir and not a saray, and the whole visit turns on that distinction.
The Tiled Kiosk, Çinili Köşk, is the oldest non-religious Ottoman building in Istanbul and the odd one out among the city's Ottoman monuments: it does not look Ottoman.
Beneath the Arasta Bazaar, the row of shops behind the Blue Mosque, lies a strip of floor that belonged to the Great Palace of Constantinople.
Turks call it Binbirdirek, "a thousand and one columns", which is a way of saying "a great many" rather than a count. The real figure is 224.
The Quincentennial Foundation Museum of Turkish Jews tells the story of a community that has been in this city far longer than most of the monuments around it.
Ihlamur is not a palace in the sense that Dolmabahçe is a palace.
This is a rented house on a busy Şişli avenue that happens to be where the Turkish Republic was decided upon. The building is a three-storey house put up in 1908.
Aşiyan is a poet's house, and the poet designed it himself. Tevfik Fikret (1867-1915) drew the architectural project for the three-storey wooden building, had it built in 1906, and lived in it until his death nine years later.
Panorama 1453 is a single artwork housed in a purpose-built rotunda, and understanding that before you buy a ticket is the difference between a good visit and a puzzled one.

District boundaries come from OSM administrative relations, so a district page holds exactly the places inside it — plus, for the islands and the coast, the nearest district by proximity.
South of the Horn, in Fatih, the monumental core is walkable end to end: Hagia Sophia, the Blue Mosque, the Basilica Cistern and Topkapı sit inside one square kilometre.
North of the Horn, Beyoğlu climbs from Karaköy to Taksim and is where the city eats and drinks late. Across the Bosphorus, Kadıköy and Üsküdar are residential, cheaper and reached best by ferry rather than by bridge.

One contactless card covers tram, metro, funicular, bus and ferry, and it is the only ticket most visitors need.
The T1 tram threads the monumental core; the M2 metro crosses the Horn to Taksim. Ferries are the fastest way between the European and Asian sides and cost the same as a tram ride. Traffic on the bridges is unpredictable enough that a taxi is rarely faster.

Three days covers the monumental core in Fatih without rushing. Five lets you add Beyoğlu, a Bosphorus ferry and one of the Asian-side neighbourhoods.
Yes, outside prayer times. Shoulders and knees should be covered, shoes come off at the door, and women cover their hair; scarves are lent at the larger mosques.
The scheduled public ferry runs the same water as the tourist cruises for a fraction of the fare, and stops at neighbourhoods you can walk around before catching the next one back.
Fatih puts you inside walking distance of the monuments. Beyoğlu is livelier at night and still two tram stops away. The Asian side is cheaper and quieter but adds a ferry to every sightseeing day.
April to June and September to October are warm without the July heat or the cruise-ship peak. January and February are cold and wet but the queues disappear.
