Bozdogan Aqueduct in Istanbul- Few of the aqueducts established to provide water to cities in the Roman period have survived.
Located in Unkapanı, in the heart of Istanbul, Bozdogan, or Valens Aqueduct, as it is known by the world, is uncommon in length and strength in the world. Today, he has been watching Istanbul for more than 1,500 years, although we do not notice it as traffic flows under it.
