| Hagia Sophia (Church of the Holy Wisdom) was built in Constantinople (now İstanbul) between 532 and 537 under the auspices of Emperor Justinian I. Innovative Byzantine technology allowed architects Anthemius of Tralles and Isidore of Miletus to design a basilica with an immense dome over an open, square space, pictured. The original dome fell after an earthquake and was replaced in 563. The church became a mosque after the Ottoman conquest of 1453, and is now a museum. |
