Turkey is the only Muslim country in which Islam is not the state religion, while Laicism is protected by the constitution. Turkish Laicism is a model in the Middle-East and the world in general. Turkey is an example of religious tolerance; for more than a century Muslims, Jews, and Christians have been cohabitating together in peace and harmony. Hagia Sophia is a symbol of harmony, peace and tolerance in Turkey. It is an important symbol in Istanbul because it is a meeting point of the world’s religions. The walls of Hagia Sophia represent a blend between Islamic arts and symbols of Christianity. Hagia Sophia was a Church, a Mosque and today it’s a museum. Every year millions of people visit Hagia Sophia to admire its architecture and feel its atmosphere of peace, harmony and tolerance throughout the centuries.
