Its story
It was built in the 6th century, in the reign of Emperor Justinian I, to meet the water needs of the Great Palace and its surroundings. The roughly 140-meter-long cistern has 336 columns supporting brick vaults. The Medusa heads used at the bases of two of the columns attract attention as spolia taken from other buildings. The structure continued to supply water to the wells of nearby houses in the Ottoman period and, after being long forgotten, became known again in the 16th century through the account of a European traveler. After a restoration completed in 2022, it reopened with a lighting design and exhibition areas.
