The Aqueduct of Valens was a Roman aqueduct system built in the late 4th century AD to supply water to Constantinople, the capital of the Eastern Roman Empire. Construction began under Emperor Constantius II and was completed in 373 by Emperor Valens, after whom it is named. The initial phase drew water from springs at Danımandere and Pınarca, stretching 268 kilometres in total length, while a 5th-century expansion added 451 kilometres of additional conduits carrying water from Vize, 120 kilometres distant. The system remained in continuous use through the Byzantine and Ottoman periods, undergoing extension and maintenance by successive rulers. The most visible surviving section, the Bozdoğan Kemeri (Aqueduct of Bozdoğan), spans the valley between Istanbul University and the Fatih Mosque in the Fatih district, its graceful arches passing over Atatürk Boulevard. This remnant, 921 metres long, stands as an important landmark testifying to the engineering ambitions of late antique Rome and the enduring infrastructure of Constantinople.
