Venue: Hagia Irene
Town: Eminönü, TR

Hagia Irene (Greek: Αγία Ειρήνη) or Hagia Eirene, sometimes known also as Saint Irene, is a former Eastern Orthodox church located in the outer courtyard of Topkapı Palace in Istanbul. It is the oldest known church structure in the city and one of only two Byzantine churches still standing in Istanbul today that were never converted into mosques, alongside the Church of Saint Mary of the Mongols, as it was used as an arsenal for storing weapons until the 19th century. The Hagia Irene now operates as a museum and concert hall. The church was dedicated to the peace of God, and is one of the three shrines which emperors devoted to God's attributes, together with Hagia Sophia (Wisdom) and Hagia Dynamis. The building reputedly stands on the site of a pre-Christian temple. It ranks as the first church completed in Constantinople, before Hagia Sophia, during its transformation from a Greek trading colony to the eastern capital of the Roman Empire. According to later tradition but disputed by some scholars, the Roman emperor Constantine I commissioned the first Hagia Irene church in the 4th century, which was completed by the end of his reign (337). When Constantine died, it is believed that his resting place may be the porphyry sarcophagus that lay in the courtyard. It served as the church of the Patriarchate before Hagia Sophia was completed in 360 under Constantius II. During the Nika revolt in 532, Hagia Irene was burned down. In the wake of the riots, Emperor Justinian I, who had almost been deposed during the riot, had the church rebuilt in 548 as part of a widespread architectural project. It was then damaged again by the 740 Constantinople earthquake on October 20, 740, about six months before the death of Leo III. The Emperor Constantine V ordered the restorations and had its interior decorated with mosaics and frescoes. Some restorations from this time have survived to the present. Throughout the history of the Roman Empire, emperors were often away from the seat
