In the east edge of Constantinople, the “City of the Cities”, the administrative and religious center of the Byzantine Empire, Hagia Sophia rises.
This magnificent monument of “God’s Wisdom” was firstly inaugurated by Constantius II and it was rebuilt in 415 by Theodosius II. Its later destruction, during the Nika Riots, gave the opportunity to Justinian to build the impressive edifice, still preserved, following the ambitious and innovative architectural proposals of Isidorus of Miletus and Anthemius of Tralles, based on the domed basilica.
