Valens Aqueduct Facts
The Valens Aqueduct is one of Istanbul’s most striking surviving Roman-era structures. It is 971 meters long, with a peak height of about 29 meters. It is not an entirely straight and regular structure because some of its components were reconstructed at various points throughout time. In contrast, the arches between 41 and 45 and 52 to 56 were rebuilt during the reigns of Mustafa II and Suleyman I, respectively. As can be seen, the arches between 1 and 40 and 46 to 51 have remained unchanged from the time of Emperor Valens.
Uncertain circumstances surround how the bent section near the Fatih Mosque got to be that way, which attracts particular notice. Even though its stonework appears to be nearly flawlessly regular from a distance, closer examination reveals that ashlar blocks and bricks were combined to build it.
The aqueduct’s breadth is also asymmetrical, with its largest point measuring 8.24 meters and its narrowest at 7.75 meters. The pillars are 3.70 meters thick and currently extend 6 meters below the surface.
If you look at the Valens Aqueduct map, you can see that the water that joins together near Edirnekapi comes from the northeast and the northwest parts of the Valens Aqueduct. The daily discharge measured in the 1950s was around 6,000 m3.
