Located near the Bab al Nahr Gate on the Orontes, this waterwheel is the largest of 17 extent waterwheels that carried water from the river to the city. In this case a substantial portion of the aqueduct, approximately 14 arcades, is still standing. It bears an inscription indicating the date of construction and indicating it was built by Aydamar Ibn ‘Abd Allah al-Sayhi al-Turki in 763 AH / 1361 CE in order to carry water to the Great Mosque of Hama.
