Hagia Irene, Istanbul
Hagia Irene, or "Holy Peace," is a Greek Orthodox church located in Istanbul, Turkey. Built in the 6th century, it is one of the few churches in Istanbul that has not been converted into a mosque. The Hagia Irene today operates as a museum and, because of its fine acoustics, a concert hall. Here it is shown in front of the more famous Hagia Sophia, which was built later.
