One of the world’s greatest structures is the Hagia Sophia in Istanbul , also known in its native tongue as Ayasofya and in Latin as Sancta Sophia (Church of the Holy Wisdom or Church of the Divine Wisdom). During the reign of Byzantine Emperor Justinian I (527–565), a Christian church was constructed there. Over the years that followed, it served as a mosque, a museum, and finally, back to a mosque. The architecture has both Islamic features (such as minarets and inscriptions) and Christian embellishments (such as mosaics) to show the evolution of religion in the region.
