The Valens Aqueduct or Bozdogan Su kemeri was built by the Roman Emperor Valens in 4th century A.D. The Romans provided water for the citizens via aqueducts and filled the cisterns.

The total water way system length was 270 km. in Constantinopolis. Eventhough the aqueducts have lost its importance, some of the parts are still standing in Istanbul. The remaining part of the Valen’s Aqueduct is 970 meters today. The Valens Aqueduct is where the Unkapani Bridge, town hall, Şehzade Mosque and the Golden Horn are located.
