The Hagia Sophia, which means ‘Holy wisdom’ in Greek, was built in Constantinople (present-day Turkey) between 532 and 537.
Built as a Greek orthodox Christian patriarchal basilica, the Hagia Sophia later served the purpose of an Imperial mosque, and is now converted into a museum. Its massive dome, which was the essence of Byzantine architecture, is considered till date to have ‘changed the history of architecture’.
Amazing Fact: The monument has a unique mixture of religions and eras and also contains a large collection of holy relics.
