The Hagia Irene Church (Aya İrini Kilisesi) is one of the oldest surviving Byzantine monuments in Istanbul, Turkey. Located within the Topkapı Palace outer courtyard, it is a historic treasure often overshadowed by the more famous Hagia Sophia. Yet Hagia Irene holds unique significance—it was the first church built in Constantinople after the Roman Empire embraced Christianity.
Today, Hagia Irene stands as a museum and concert hall, offering visitors a chance to explore Byzantine architecture, early Christian art, and the deep religious history of Istanbul.

Hagia Irene was commissioned in the 4th century by Emperor Constantine I after he declared Christianity as the official religion of the Roman Empire. It predates Hagia Sophia by nearly two centuries.
After a fire in 532 (during the Nika Revolt), Emperor Justinian I rebuilt Hagia Irene, around the same time he commissioned Hagia Sophia.
Unlike many other Byzantine churches, Hagia Irene was never converted into a mosque after the Ottoman conquest of Constantinople (1453). Instead, it was used as an armory and weapons depot, preserving much of its original Christian architecture.
Today, Hagia Irene is a museum under the Turkish Ministry of Culture and Tourism. It is also renowned for its classical music concerts due to its exceptional acoustics.
