The Basilica Cistern is a massive, cathedral-sized underground water reservoir built during the 4th century. It was enlarged in 532 AD, during the reign of Emperor Justinian I, with the purpose of supplying water to the Great Palace and surrounding areas. The cistern stores up to 80,000 cubic meters of water, delivered via 20 kilometers of aqueducts from a reservoir near the Black Sea.
The site is surrounded by a firebrick wall that is 4 meters thick and waterproofed with mortar to prevent leaks. Visitors descend fifty-two stone steps into the cistern, where they encounter columns, water reflections, and atmospheric lighting that highlight the grandeur of this ancient engineering feat. The water source is traced through the Erikap Water Distribution Center in the Belgrade Forest, connected via the Valens Aqueduct and the Malova Aqueduct.
The guide explains how this underground structure played a vital role in Istanbul’s water supply during Byzantine times and how its architecture has stood the test of time. This background enhances appreciation for the engineering skills of the ancient Byzantines and the importance of water management in historical cities.
