Topkapı Palace unfolds as four walled courtyards, low pavilions and gardens spread across Seraglio Point, the headland where the Golden Horn, the Bosphorus and the Sea of Marmara meet. There is no grand facade to stand in front of; the palace reveals itself one gate at a time, each courtyard quieter and more restricted than the last. Behind the Gate of Felicity only the sultan's closest circle passed. Mehmed II laid the plan out after his conquest of 1453, and for nearly four centuries several thousand people lived and worked inside the walls as a self-contained city.
You walk it gate by gate, from crowded outer courts into cool tiled rooms where the city noise drops away. The Treasury holds an emerald-set dagger and jewelled thrones; the old kitchens show Chinese porcelain by the thousand; a marble terrace opens without warning onto the Golden Horn. The Harem is a separate visit rather than a room along this route, entered through its own Carriage Gate off the second courtyard. Many people walk past that gate without knowing it is there. The Sacred Relics rooms, where a reciter still reads the Quran aloud, stay the most hushed spaces in the city.
