Basilica Cistern (Entry)

Basilica Cistern (Entry) introduces an underground water reservoir beneath Istanbul, built during the Byzantine Empire in the sixth century. Emperor Justinian commissioned this reservoir for Constantinople’s Great Palace.

Inside, massive marble columns create a forest of supports, with individual decoration shaping the cistern’s distinctive atmosphere. Shallow water reflects the columns.

The broad cistern once stored water for Constantinople during sieges, linking underground engineering with the city’s imperial history. Medusa heads serve as unusual column bases.

Their origin and purpose remain unknown, adding a mythological question to the architectural setting. A perpetually damp Weeping Column draws attention.

Local belief connects its moisture with healing powers, while the surrounding water preserves an eerie visual character. The site also appeared in popular films.

Raised wooden platforms let visitors view the columns, reflections, and architectural details above the shallow water. The Great Palace connection explains the reservoir’s role.
