Admire the marble columns and Corinthian capitals

Learn about the waterworks of ancient Constantinople

The cistern was built during the reign of Emperor Theodosius II (AD 408–450) to supply water to the main buildings of the Byzantine capital. Rediscovered during restoration work in the early 21st century, it was carefully preserved and opened in its current form. Unlike the city's busier attractions, you can enjoy its history and architecture in a quiet atmosphere.
