The Second Largest Church After Hagia Sophia: The Hagia Irene located in the outer courtyard of Topkapı Palace is the oldest church of the Eastern Roman Empire (Byzantine). It was also the second largest church in Istanbul after Hagia Sophia. Hagia Irene, originally means “sacred peace” (Hagia Eirene), has a special meaning as the first place where Turkish museology was born. Hagia Irene, a typical Byzantine structure with its materials and architecture, was built on the site of an old temple in 330. During the reign of Emperor Justinianus, the Nika Revolt in 532 led to the devastation of both Hagia Sophia and the Hagia Irene, and two of them were rebuilt together.
