The Palace That Drowned Beneath Istanbul | Basilica Cistern

The Basilica Cistern (Yerebatan Sarayı) in Istanbul, Turkey, built in 532 AD under Emperor Justinian, is an underground palace of 336 marble columns, home to the mysterious upside-down Medusa heads. Beneath the streets of Istanbul lies a palace with no king — 336 columns, an underground lake, and a face turned upside down that no one can fully explain. This is the story of the Basilica Cistern: how it was built, how an entire city forgot it existed, and the mystery still sitting in its darkest corner. Built in 532 under the emperor Justinian to secure Constantinople's water, the cistern was hidden, abandoned, and lost to memory for centuries — until a traveler followed strange rumors down into the dark and rediscovered a drowned palace beneath people's own homes. And in the far corner, two enormous Medusa heads, reused as simple stone blocks. One on its side. One completely upside down. After 500 years, we still don't know why. Anatolia has been the crossroads of civilizations for twelve thousand years.
