Theodosius Cistern

Cisterns were a common sight in Constantinople, aka the capital of the Byzantine Empire. Since there were no rivers nearby, the city relied on a system of aqueducts to meet its water needs. And as Constantinople was much-coveted, it was crucial to have large reservoirs of drinking water in case of a siege. This cistern is smaller and much older than the one of the basilica. As its name suggests, it was built under Theodosius II as early as the 5th century. It has been restored over a period of 8 years, and it's now open to the public as a concert hall, equipped with a special lighting system! Here’s your chance to see the cistern in a totally new light! Remember to check the schedule for upcoming performances.
