Basilica Cistern

When wandering through the heart of Istanbul, one can't help but be drawn to the allure of its ancient wonders. Among these, the Basilica Cistern stands out as a marvel of architectural ingenuity. Nestled just southwest of the iconic Hagia Sophia, this vast underground reservoir was commissioned by Emperor Justinian I during the Byzantine era, between 527 and 565 AD. Locally, it's affectionately known as the "Yerebatan Cistern," which translates to "Cistern of the Sunken Palace," owing to the mesmerizing forest of marble columns that rise from its depths.

The Basilica Cistern is an awe-inspiring sight, stretching over a rectangular space that's 140 meters long and 70 meters wide. Encompassing a total area of 9,800 square meters, it once held a staggering 100,000 tons of water. As you descend the 52-step stone staircase, you enter a world supported by 336 columns, each standing 9 meters tall. These columns are spaced 4.80 meters apart, forming 12 rows of 28 columns each. Many of them are believed to have been sourced from older structures, showcasing a variety of marble types and craftsmanship. Some are carved from a single piece, while others are composed of two pieces. The cistern's walls, a solid 4.80 meters thick, were constructed from bricks and reinforced with a thick layer of Horasan mortar, ensuring they remain impervious to water.

Beyond its architectural grandeur, the Basilica Cistern offers a unique atmosphere, with dim lighting and the sound of water droplets creating an almost mystical experience. It's a place where history feels alive, whispering stories of ancient times. As you explore, keep an eye out for the famous Medusa heads that serve as column bases, adding a touch of mythological intrigue to this subterranean wonder.
