Bozdogan Belt

The information about the first construction of the Bozdoğan Aqueduct is not certain. It is known that some water facilities were built in Istanbul towards the year 123 during the reign of Roman Emperor Hadrian, but it is not clear to what extent the Bozdoğan Aqueduct is related to them. After the city was re-established in 300 by Konstantinos I, the facilities were also renovated. It is generally accepted that the arch was built by the Roman Emperor Valens (364-378), and for this reason it is also known as the "Valens Aqueduct".

It has not been clarified yet when and how the work, which is mentioned only with the name Kemer in Fatih foundation charters, got its current name.

The original technical features of the Bozdoğan Aqueduct, which was built with neat cut stones, can be seen in the 25th eye, which has survived in the best condition.

Bozdoğan Aqueduct, one of the oldest works of Istanbul, helped to meet the water needs of the city in the Late Roman and Byzantine periods and continued this service as a part of the city's water network throughout the entire Ottoman period.
