Originally built in the 6th century, its large central dome is said to have changed the history of architecture. It’s a magnificent example of the Byzantine style, and features golden mosaics which were covered during the 500 years when it served as a mosque.

It’s surrounded by six tall minarets, and has a wide central dome with eight smaller ones cascading from it. There are over 200 stained glass windows, which provide plenty of natural light inside.
