The historic Yerebatan (Basilica) Cistern, which is Turkey’s third most visited spot in Istanbul’s historic Sultanahmet district, has been undergoing a comprehensive restoration process for the first time after 500 years.
The restoration, carried out by Hera Restoration, will last for 450 days and end on March 11, 2018. The cistern will be open to visitors during the restoration process.
The works are expected to rearrange the entrance and exit sections of the cistern due to overcrowding at the entrance of the cistern, where visitor queues have occasionally extended to the streets and caused discomfort among visitors. The entrance will be covered with a glass roof and a waiting area will be built.
