Hagia Sophia Museum / Ayasofya / Santa Sofia Built in the 6th century by Emperor Justinian, played a very important role in the Christian and Islamic World. After the Ottoman conquest the bells, altar, iconoclastic, and sacrificial vessels were removed, and many of the mosaics were eventually plastered over to convert the church into a mosque then a museum and now it’s a mosque for the second time. The most important stop of an Istanbul tour is operated in Old City Istanbul / Constantinople. *Please note that as it's not a museum anymore, tour guides don't have skip-the-line priority there.
