Landmark

Hagia Sophia, officially the Hagia Sophia Grand Mosque, is a mosque in Istanbul, Turkey. Initially built by the eastern Roman emperor Justinian I as the Christian cathedral of Constantinople for the state church of the Roman Empire between 532 and 537, and designed by the Greek geometers Isidore of Miletus and Anthemius of Tralles, it was formally called the Church of the Holy Wisdom and was then the world's largest interior space and among the first to employ a full pendentive dome. It is considered the epitome of Byzantine architecture and is said to have "changed the history of architecture". — Wikipedia
