Basilica Cistern is an underground water palace in the heart of Istanbul. 336 columns support the vaults of this ancient reservoir built under Emperor Justinian. In the dimness, with the sound of dripping water — a sense of another world.

History

The cistern was built in 532 under Justinian I. Dimensions: 140 by 70 meters, capacity 80,000 cubic meters. It supplied water to the Great Palace of Byzantine emperors. The name "Basilica" comes from a temple that stood here earlier.

Columns and Medusa Heads

336 columns from various ancient temples — marble, granite, different styles. In the far corner — two giant Medusa Gorgon heads as column bases. One sideways, one upside down — a mystery that attracts tourists.

Modern Cistern

About half a meter of water, carp swim among columns. Colored lighting creates a mystical atmosphere. Wooden walkways are laid for viewing.
