A first glimpse of what you'd see after you'd entered through the Imperial Gate: the St. Irene (Haghia Eirene) church, the church of the devine peace. It was one of the first churches in the old Byzantium, and has been rebuilt by Constantine the Great or his son Constantinus. It was the cathedral of the patriarch until the Haghia Sophia was finished. After that church had been destroyued in 404 it became the cathedral for another ten years. I created a special St. Irene gallery within the Topkapı complex.
