CommonMachine translated — This content was machine-translated and may differ from the original Turkish text.

A giant 6th-century Byzantine underground reservoir where hundreds of columns rise from the water in dim light.

Safety warning

The cistern has been managed by the General Directorate of Foundations since 2 June 2026 and reopened to visitors on 6 June 2026. The floor may be damp and slippery; it is dim inside.

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.
