Theodosius Cistern, Ancient Roman cistern in Fatih, Turkey
The Theodosius Cistern stretches across 960 square meters beneath Istanbul, supported by 32 marble columns with Corinthian capitals and 45 vaulted ceilings.
Built during the reign of Emperor Theodosius II between 408 and 450 CE, this underground water storage facility supplied Constantinople through water channels from outside the city.
The cistern represents Byzantine engineering methods with its rectangular structure, featuring windows placed at regular intervals to prevent water deterioration and provide ventilation.
The cistern opens daily from 9 AM to 7 PM, with entrance fees of 150 TL for adults, 50 TL for students, and 650 TL for international visitors.
This structure incorporates a 360-degree projection mapping system, making it the oldest building in the world to feature such technology for historical presentations.
