Valens Aqueduct: A Marvel of Roman Engineering

Overview

The Valens Aqueduct, a stunning example of Roman engineering, played a crucial role in supplying water to the ancient city of Constantinople for centuries. Commissioned by Emperor Hadrian between 117 and 138 AD, this aqueduct underwent significant restorations and expansions, notably during the reigns of emperors Valens and Theodosius I. Standing at an impressive height of 19 meters, its elegant double-story arches span a length of 970 meters, with 625 meters still intact today. While primarily an underground water system, the majestic arches continue to be a striking feature of the landscape, representing both the ingenuity of ancient Rome and the rich history of water management in the region. Today, visitors to Istanbul can appreciate the significance of the Valens Aqueduct as an architectural landmark that connects the past to the present.

This remarkable structure spans a busy highway today, serving as a reminder of the impressive aqueduct system that once supplied water to Constantinople during Roman times. It is named after Emperor Valens, who oversaw its construction.

The aqueduct is truly magnificent! Its historical significance and stunning architecture create a journey back in time as you walk through its arches, leaving you with unforgettable impressions. While it can be noisy due to traffic, heading to nearby MatoEt restaurant or Fatih Memorial Park provides a peaceful view of this majestic landmark. Definitely worth a visit!

A historical and architectural wonder whose sheer scale can only be appreciated in person. It's a short walk from the Istanbul University metro station and the mausoleum of Destari Mustafa Pasha. If you enjoy architecture, history, capturing photographs, or are simply a tourist looking for sights, this is a must-visit location.

The Aqueduct of Valens (Bozdoğan Kemeri), also known as Valens Su Kemeri, is a remarkable historic site located in Istanbul, Turkey. It stands as a testament to Roman engineering and remains one of the most significant remnants of ancient infrastructure in the city. Built in the 4th century under Emperor Valens to bring fresh water to Constantinople (modern-day Istanbul), its impressive series of arches illustrate the blend of functionality and grandeur. The aqueduct, stretching for several kilometers, played a crucial role in supporting the city's population, baths, fountains, and palaces during the Byzantine period and beyond. Unique in its preservation amidst a modern city, this enduring symbol of the Roman Empire is not just a landmark but an active piece of history still integrating with contemporary landscapes.

It's large and well-maintained. A few lights added would enhance its beauty at night.
