The Hagia Sophia (or “Aya Sofya” in the local language) was an old Christian church that was built in the 6th century during the Byzantine Era of Constantinople. Later, after the conquest of the city and its name-change to Istanbul, it became a mosque. Nowadays, it is a museum and a main attraction in Istanbul.
