Saying that problems arose because of the corridors, Hagia Sophia Museum Director Ahmet Haluk Dursun explained: “There is the same danger of humidity in the ground. We are trying to balance the water under the structure. When it exceeds 1 meter, this is a danger signal for us. But we are lucky that the structure is on rocky ground. Humidity can destroy Hagia Sophia.”
According to information provided by Dursun, the number of visitors reached a record level last year, as 2.5 million people visited the museum.
