Constructed in the 5th century during Emperor Theodosius II’s reign, the Theodosius Cistern (also known locally as Erefiye Sarnıcı) served as an underground water reservoir crucial for providing the city with clean water during Byzantine times. Unlike the more famous Basilica Cistern, this site tends to be less crowded, offering a more intimate glimpse into ancient engineering.

What Do Visitors Say?

Reviews highlight a mixed experience: some praise the “skvlá prohlídka” (great tour) and the immersive atmosphere, while others have expressed disappointment, especially in comparison to larger cisterns like Basilica. One reviewer called it “a fascinating visit,” emphasizing the quiet, contemplative environment and the informative narration. Conversely, another reviewer felt it was “beter de basilica cisterne,” pointing out it’s smaller and less grand, which may influence expectations.

Another useful insight from visitors is to wear comfortable shoes and to be mindful of the slippery floors, especially since the cistern is underground and can be cooler than the outdoor temperature.

To maximize your visit, arrive early or at your designated start time to avoid the crowds. Bring a small flashlight if you’re particularly sensitive to dark environments, although the lighting is generally sufficient.

Who Should Consider This Tour?

This underground cistern is perfect for those interested in the architecture, engineering, and history of ancient Istanbul. It’s ideal for travelers who appreciate self-guided exploration with informative narration and aren’t put off by the cool, damp environment.
