Cisterna Basílica Estambul

Hidden beneath the vibrant streets of Sultanahmet lies the Basilica Cistern Istanbul, a breathtaking underground structure that once supplied water to the Great Palace of Constantinople. Built in the 6th century during the reign of Emperor Justinian I, this vast reservoir is one of the city’s most atmospheric and mysterious landmarks.

Visitors can explore its towering marble columns, dimly lit walkways, and the famous Medusa Heads that have fascinated travelers for centuries. The cool, quiet ambiance and modern light installations create a unique blend of ancient engineering and modern art.

A visit to the Basilica Cistern is like entering a forgotten world—silent, sacred, and surreal. Whether you're drawn by its history or its haunting beauty, it remains a must-see highlight of Istanbul.

The Basilica Cistern was commissioned by Byzantine Emperor Justinian I around 532 AD after a major uprising left parts of the city in ruins. It was built to serve as a water reservoir for the imperial complex and surrounding areas.

Constructed using recycled materials, the cistern features architectural elements from earlier Roman structures, including two Medusa Heads at the base of columns. During the Ottoman era, it was largely forgotten, only to be rediscovered in modern times.

Today, it stands as a remarkable reminder of Byzantine engineering, preserved as one of Istanbul’s most iconic heritage sites.
