This large underground cistern is built by the Byzantine Emperor Justinian (527-565) to solve the drinking water problem in the city. The Basilica Cistern was used for a while after the conquest of Istanbul by the Ottomans in 1453 and water was supplied to the gardens of Topkapı Palace, where the Sultans lived. 

The water from the cistern was still water. That’s why it was not preferred by some of the Ottoman Sultan who liked to drink running water. After some water facilities were established in the city, the Cistern was completely forgotten until it was rediscovered by the Dutch traveler P. Gyllius who visited Istanbul to investigate the Byzantine ruins.

When the Cistern was unearthed, it was not in a condition to be used and required a massive renovation. The biggest renovation project during the Republican period was initiated by the Istanbul Municipality in 1985. With the removal of 50,000 tons of mud and the construction of the excursion platform, it was completed on September 9, 1987, and reopened to visitors. 

The Basilica Cistern became one of the top tourist destinations since then. This place attracts millions of travelers each year due to its historical and impressive atmosphere. You can visit the Basilica Cistern with the Istanbul Tourist Pass® to skip the ticket lines and save time and money on your Istanbul trip.
