One of the legends of Hagia Sophia is that its dome, which was incredibly wide for the time it was built, was carried by angels. 4 Seraphim angels each with 6 wings have been decorating the walls of Hagia Sophia for over 1000 years. No one noticed that they were flying, although over a billion people passing under admired them.

“Flight of the Angels” was probably a secret that only belonged to an elite group for centuries and was only shown to very special people, through a mirror system or a similar contraption. When the city conquered by the Ottomans, Hagia Sophia was turned into a mosque and the secret was buried deep in history.

Now, the “secret” comes back to life in all its glory thanks to digital technology.
