Theodosius Cistern is located in Sultanahmet, one of the most popular touristic centers of Istanbul. There are light shows every hour in the cistern, which was recently restored and opened to visitors.
The most famous cistern in Istanbul is the Basilica Cistern from the reign of Emperor Justinian. But Theodosius Cistern is essentially even older than Basilica Cistern. This cistern takes its name from Theodosius II, who made many architectural contributions to Istanbul.
There is also a third cistern, the Cistern of Philoxenos, in Sultanahmet. Of the three, Theodosius Cistern is the smallest when ranked in size. However, as this is the most recently restored cistern, visiting it is a wonderful experience for those who trace Roman (and Byzantine) history.

Why Were Cisterns Built?
Istanbul was actually a Greek colony founded in the 7th century BC. In this period, its name was Byzantium. The name of the city came from Byzas, who came here from Ancient Greece and founded the city.
Although the small town of Byzantium was established in a water-scarce area, it could survive by storing rainwater. Early settlers were minimally affected by the very dry nature of the Historical Peninsula (Constantinople).
However, Byzantium became the eastern capital of the Roman Empire in the 300s. When Emperor Constantine moved his throne here, Constantinople suddenly became one of the most populated cities in the world.
Members of the Roman Senate and Roman nobles had moved to Constantinople. The place known today as the Sultanahmet district had suddenly become the royal area of the “New Rome” city.
Iconic structures such as the Hippodrome of Constantinople, the Great Palace, the Baths of Zeuxippus and the Hagia Sophia were built here over time. For this reason, the need for water in the center of the capital had increased tremendously.
The largest aqueduct project of late antiquity began to be built to meet the capital’s water needs. Thanks to this water system, which was completed during the reign of Emperor Valens, drinking water could be brought to Constantinople from hundreds of kilometers away.
The water carried to the city from this aqueduct was stored in three giant cisterns built in the area known today as Sultanahmet (the eastern end of the Historical Peninsula). Thus, water could be supplied to the imperial structures I mentioned above.
