Cistern of Theodosius

Walk through the cistern and take in the cistern's 32 towering marble columns and vaulted ceilings, a striking display of ancient craftsmanship. These stone pillars, reflected in the shallow waters below, capture the ingenuity of 5th-century builders who created a reservoir strong enough to endure centuries of change in Constantinople.

Experience Turkey’s first museum-scale 360° projection show, which brings Istanbul’s past to life. Inside the cistern, the walls and ceilings turn into a panoramic screen, surrounding visitors with light and sound that transform the underground space into a living story. Pause to watch as the origins of the Theodosius Cistern unfold, along with the city’s ancient water system and the vital role these underground structures played in sustaining Constantinople, through detailed visuals and narration.

Escape the city’s crowds and step into a serene, cathedral-like chamber where history and architecture surround you in an intimate setting. Unlike the larger cisterns of Istanbul, this one feels smaller and quieter, giving you the chance to walk slowly among its marble columns without distraction. In the stillness, you’ll find a calm, almost personal atmosphere that makes it easy to reflect and connect with the city’s past.

Conveniently located near Hagia Sophia and the Basilica Cistern, the Theodosius Cistern is an easy stop to add to your day in Istanbul’s historic heart. With so many landmarks within walking distance, you can combine your visit effortlessly with other highlights. Spend the morning exploring Hagia Sophia, step into the cistern around midday, and then continue on to the Hippodrome or Blue Mosque. Afterwards, take time to browse the nearby shops, cafés, and bazaars, rounding out your itinerary with a mix of history, culture, and local life.
