Hidden beneath the bustling streets of Istanbul’s historic Sultanahmet district lies the Basilica Cistern, one of the city’s most fascinating and atmospheric landmarks. Known in Turkish as Yerebatan Sarnıcı (Sunken Palace), this ancient underground water reservoir is a masterpiece of Byzantine engineering and a must-visit destination for anyone exploring Istanbul. With its dimly lit corridors, towering columns, and mysterious ambiance, the Basilica Cistern offers a unique journey into the past.

The History of the Basilica Cistern

The Basilica Cistern was built in 532 AD during the reign of the Byzantine Emperor Justinian I. It was constructed to meet the water needs of the Great Palace and other buildings in the area. The cistern was built on the site of an earlier basilica, which is why it is called the “Basilica Cistern.” It is the largest of hundreds of ancient cisterns that lie beneath Istanbul.

The cistern was forgotten for centuries after the Ottoman conquest of Constantinople (Istanbul) and was rediscovered in 1545 by the French traveler Petrus Gyllius. Since then, it has been restored and opened to the public as a historical site.
