Bozdoğan Aqueduct (Valens Aqueduct), Istanbul

The Bozdoğan Aqueduct, also known as the Valens Aqueduct, is one of Istanbul’s most remarkable historical landmarks. Built during the late Roman period, it has stood the test of time and continues to be a symbol of the city’s rich past. Located in the heart of Istanbul’s Historical Peninsula, this grand aqueduct once played a crucial role in supplying water to the ancient city of Constantinople. Today, it serves as a breathtaking reminder of the architectural and engineering brilliance of the Byzantine Empire.

Historical Background

The Bozdoğan Aqueduct was commissioned by Roman Emperor Valens and completed in 378 AD. It was constructed to enhance the city’s water supply system, which was essential for sustaining Constantinople’s growing population. The aqueduct was part of an extensive network that transported water from distant sources in Thrace to the urban reservoirs and cisterns, including the Basilica Cistern and Binbirdirek Cistern.

Following the fall of the Western Roman Empire, the Byzantine rulers continued to maintain and expand the aqueduct. It remained a vital infrastructure component throughout the Byzantine and Ottoman periods. During the reign of Ottoman Sultan Suleiman the Magnificent in the 16th century, the structure underwent significant restorations by the famous architect Mimar Sinan, ensuring its continued functionality.

Architectural Features

The Bozdoğan Aqueduct stretches across 921 meters with an average height of 28 meters at its highest point. The structure was built using limestone and granite, materials that contributed to its remarkable durability over centuries. It consists of two tiers of arches, a characteristic design of Roman aqueducts, providing both stability and aesthetic grandeur.

Despite the changes in the surrounding cityscape, the aqueduct remains largely intact. Modern roads pass beneath its towering arches, creating a striking contrast between Istanbul’s ancient and contemporary landscapes.

Significance and Legacy

The Bozdoğan Aqueduct is not just an architectural marvel; it is a testament to the advanced engineering skills of the Roman and Byzantine eras. It also played a crucial role in shaping Istanbul’s development by ensuring a steady water supply for centuries. Even though it no longer functions as an aqueduct, its historical importance endures, attracting visitors, historians, and architects fascinated by its grandeur.
