After the conquest of 1453 by the Ottomans, Sultan Mehmed II immediately ordered repairs and refurbishments to be made. Regardless of what the state of the aqueduct bridge was before the new restoration, Al-Wardi still spoke highly of it before his death in 1457. He focused on installing forty fountains in the valley below the Valens aqueduct bridge, to which the renovated Ottoman system owes its name: the Forty Fountains (Kırkçeşme) Waterway. This refurbished waterway system also incorporated parts of the Hadrian Waterway, including the sources at Cebeciköy (see map at installation page). Tursun Bey (1453) praises the restorations extensively. Kritovoulos, Mehmed’s biographer, likewise praises ‘an abundance of water’. The repairs and adjustments of the Ottomans ensured that the higher part of the new Ottoman capital continued to be supplied with fresh water.
