Topkapi, Palace of Conquest

After Constantinople's capture in 1453, Mehmed II — "the Conqueror" — has Topkapi Palace erected from 1460 on the peninsula's southeast point, facing the Bosphorus and Golden Horn. Unlike European castles, Topkapi is an ensemble of pavilions and successive courtyards, organized according to Ottoman nomadic tradition rather than a single block. The harem, enlarged under Suleiman the Magnificent, becomes a closed world of several hundred people. The treasury houses the Spoonmaker's Diamond and Constantine's crown relics. In the eighteenth century, the Tulip Era there mixes nocturnal festivities, poetry and European diplomacy in gardens overlooking the sea.

Mehmed II chooses a strategic location: the old Byzantine acropolis, where the Hellespont narrows. The palace isn't meant to be a fortress — the city is already conquered — but the sultanate's administrative and ceremonial center. The first constructions include the Imperial Pavilion and Royal Gate, with their blue Iznik tiles.

Topkapi grows through successive additions: the Divan Hall for the state council, the Tower of Justice, the sultan's private apartments. Each reign superimposes its style — Persian, Ottoman, late European Baroque. The harem, far from being a simple place of pleasure, is a political institution where sultans' mothers and favorites exercise real influence on appointments and alliances.

The treasury preserves weapons, armor, jewels and liturgical objects. The Spoonmaker's Diamond, eighty-six carats, is surrounded by legends: found in a dump, exchanged for three wooden spoons. Muhammad's relics and prophets' attributes attract pilgrims and diplomats.

In the nineteenth century, Abdülmecid I moves the court to Dolmabahçe Palace, more European. Topkapi becomes museum in 1924, after the Ottoman Empire's fall. Its terraces overlooking the Bosphorus still recount the 1453 conquest and the transformation of a Christian city into Muslim capital.
