Eyüp Sultan grew around a grave that vanished for eight centuries, then was found again. The tomb belongs to Abu Ayyub al-Ansari — companion and standard-bearer of the Prophet Muhammad — who died besieging Constantinople with the first Arab armies in the 670s. After the Ottoman conquest of 1453, his burial place was located just outside the city walls, and Mehmed the Conqueror raised a mosque over it, the empire's first great monument beyond the ramparts. Here each new sultan was girded with the Sword of Osman, the nearest thing the Ottomans had to a coronation.
You reach it at the tip of the Golden Horn, where pilgrims file past a silver-grilled tomb lined in İznik blue and the courtyard fills with families marking circumcisions and a child's first prayers. Above, one of Islam's most sought-after cemeteries climbs the slope, its turban-topped headstones tilting under black cypresses. A cable car — or a walk up through the graves — lifts you to the Pierre Loti hill, named for the French novelist who once watched the water from a café here. Today tea gardens crowd the crest and the Horn unspools far below.
