Reviews Summary

Visitors praise the Theodosius Cistern for its impressive historical architecture and captivating light show, offering a more tranquil experience compared to the crowded Basilica Cistern. Some note that student ticket prices should be verified.

"Underneath Istanbul are many ancient cisterns to help store water thousands of years ago. This one is an alternative to the Basilica Cistern and cheaper to get in.

Go inside and purchase tickets. It’s around $25, but much cheaper for locals. (As it should be.) Walk down the stairs to the dark space where a light show plays for around 10 minutes. It’s a unique experience but worth it only once in my opinion.

It is wild to think this cistern was lost for years before rediscovered."

Austin Graff

"The Cistern of Theodosius is a small but atmospheric historical site, beautifully lit and well-preserved. The lighting and sound design create a mysterious mood that gives you a real sense of Istanbul’s ancient layers beneath the city. It’s certainly interesting — especially if you’re a fan of Byzantine history or architecture.

However, the experience felt quite short, and the entrance fee is steep for what you actually get. Compared to the nearby Basilica Cistern or other historical attractions in Istanbul, this one just doesn’t offer enough to justify the price — especially for backpackers or budget-conscious travelers.

Glad I saw it once, but I wouldn’t necessarily recommend it unless you’re really passionate about cisterns or have extra time and money to spare."

Daniel Vancouver

"The light show here is impressive, and a really beautiful and quiet cistern. Is wheelchair accessible. Could do with some seating and is a little expensive."
