Hagia Irene Church In Istanbul Royalty-Free Stock Photo

The building reputedly stands on the site of a pre-Christian temple. It ranks, in fact, as the first church built in Constantinople. Roman emperor Constantine I commissioned the first Hagia Irene church in the 4th century. From May to July 381 the First Council of Constantinople took place in the church. It was burned down during the Nika revolt in 532. Emperor Justinian I had the church restored in 548. It served as the church of the Patriarchate before Hagia Sophia was completed in 360.
