The First Church of Constantinople
Hagia Irene is the first church built in Istanbul and was constructed by Roman Emperor Constantine in the 4th century. The name “Hagia Eirene” means “Holy Peace” in Greek, but it is also associated with Saint Irene, originally named Penelope, who devoted her life to spreading Christianity.
During the Byzantine Empire, Hagia Irene stood alongside Hagia Sophia as one of the city's most significant religious structures. The church underwent multiple reconstructions; its original wooden structure was destroyed in the Nika Riots of 532. Later, Emperor Justinian rebuilt it, but it burned again in 564. Over time, earthquakes damaged the structure, leading to multiple restorations.
After the Ottoman conquest of Constantinople in 1453, Hagia Irene was not converted into a mosque, unlike many other churches. Instead, it was used as an arsenal and a military storage facility
