The Cistern of Theodosius: A Hidden Treasure in Istanbul

Beneath the busy streets of Istanbul, you'll find the Cistern of Theodosius (also known as the Serefiye Cistern), an ancient structure that offers a fascinating glimpse into the city's rich history and impressive engineering. While many tourists visit the famous Basilica Cistern, the Cistern of Theodosius remains a hidden gem, showcasing the engineering prowess of the Byzantine era.

From Byzantine to Ottoman Times

The Cistern of Theodosius was built during the rule of Emperor Theodosius II (408-450 AD) to store water for the city, especially during droughts or attacks. It was later expanded by the Ottomans, who left their mark on the structure. The cistern's design and its large, marble columns demonstrate the high level of craftsmanship of its builders.

Beautiful and Strong Design

Measuring 24 by 40 meters and with a ceiling 11 meters high, the Cistern of Theodosius is supported by 32 columns made from marble from Marmara Island. The walls are coated with a special plaster to prevent leaks. The thick walls and curved corners were designed to endure immense pressure, with 45 sail-shaped vaults that blend function and beauty in a harmonious design.

Rediscovered and Restored

The cistern was hidden for centuries, but in 2010, nearby buildings were demolished, revealing the structure. It was subsequently restored, and an archaeological park was built around it. The area has changed a great deal over time, with the Arif Pasa Estate, built in the 18th or 19th century, once serving as the location for city offices.
