For people visiting Turkey, the Hagia Sophia is top of the must see list; this is not surprising, the Hagia Sophia has been described as ‘a heritage not only of Turkey, but also of the world.'
On average, Istanbul’s Hagia Sophia Museum gets about 2.5 million visitors a year; however, Japanese experts suspect that human breath increases the humidity level in the Hagia Sophia Museum causing damage to the ancient building. They will be making tests in the New Year to confirm this theory.
If the team of Japanese experts determine that human breath causes an increase in humidity levels, a quota will be imposed on the number of visitors to the museum.
A reduction of people visiting will be a shame, as the Hagia Sophia in Istanbul is one of the main attractions that bring people to Turkey in the first place.
