"During this same period, Constantine built a number of churches. In them, he departed entirely from the architectural style of the pagan temple, evolving instead a new form of the Roman secular building, the basilica - a not inappropriate choice since Church was now equated with State. [...] Of the churches, the first was that of Hagia Irene, the Holy Peace. It stood on the same spot that a temple of Aphrodite had once occupied - a spot occupied today by a sixth-century Byzantine structure. The adjoining site was designated for the first church of Hagia Sophia, the Holy Wisdom, planned by Constantine but built by his son and successor, Constantius II."
