The Theodosius Cistern, also known as Şerefiye Cistern, is a 1600-year-old Byzantine water reservoir in Istanbul. Unlike the more famous Basilica Cistern, it offers a unique, immersive light show that brings its ancient history to life, making it a truly engaging visit.

Don't miss the immersive 10-minute light show, which transforms this ancient cistern into a captivating historical and artistic experience.
In their own words: “My fifth and final recommendation for you guys to come visit Şerefiye Cistern or Theodosius. It's built 1600 years ago during the reign of Theodosius II... This has a serious surprise and it's fitted with projectors. You can enjoy the light show, which is the oldest building where that system has been installed, and it is absolutely mind-blowing. This is also the only place where you'll need to buy a 150 Lira ticket, but honestly it's seriously worth it.”
