Valens Aqueduct
This Roman aqueduct from the 4th century supplied water to Constantinople for over a thousand years. It cuts right through the modern city, so you can walk right up to it.
The Valens Aqueduct, known locally as Bozdoğan Kemeri, is a massive piece of Roman engineering that started under Emperor Constantius II and was finished by Valens in 373 AD. It was the main water supply line for the Byzantine capital and was so vital that both the Byzantines and later the Ottomans kept maintaining and extending it for centuries.
Today, its most famous section is the double-tiered archway that spans Atatürk Bulvarı. It's not a fenced-off museum piece; it's fully part of the city's fabric. You can stand underneath its arches and watch the traffic flow, which makes the history feel very immediate.
“See ancient Roman infrastructure still holding up a modern highway.”
The best view is from the pedestrian walkway on the south side of Atatürk Bulvarı, near the Vefa High School gate.
Viewing is from public sidewalks which are step-free, but crossing the busy boulevard requires using underground passages with stairs.
