During the late Byzantine period it wasn't used much and fell into ruins, than restored by the Ottomans after the Conquest of the city and served for some time to carry water again. Over the centuries, it was badly damaged because of disuse and roads and buildings constructed on and around it. Today only bits and pieces left from the original aqueducts on its way from the forest to the city center, and in Sarachane neighborhood there is a 900 meter long part of it, namely Bozdogan arch. The Municipality of Istanbul started the restorations in 1998.
