Eyüp Sultan is a pilgrimage mosque at the tip of the Golden Horn, built over the grave of Abu Ayyub al-Ansari, companion and standard-bearer of the Prophet Muhammad. 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 the mosque 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.
Abu Ayyub died besieging Constantinople with the first Arab armies in the 670s, and his burial place was located again just outside the walls after the Ottoman conquest of 1453. Mehmed the Conqueror raised a mosque over it, the empire's first great monument beyond the ramparts, and each new sultan was girded here with the Sword of Osman, the nearest thing the Ottomans had to a coronation. Tea gardens crowd the hilltop, named for a French novelist who watched the water from a café here, and the Horn unspools far below.
