Cee’s Fun Foto Challenge: Circles and Curves

The Blue Mosque may be the most well known landmark in Istanbul, but right opposite it, lies the Hagia Sophia, a structure constructed as a Greek orthodox church in the year 537. Later it was converted to a Roman Catholic cathedral and in 1453 it became a mosque under the Ottoman Turks. Finally it was converted to a museum in 1935.

You can see plenty of circles and curves in its exterior and interior structure.
