Persian Domes (Mosques)

Persian architecture of domes could be dated back to the earliest Mesopotamian domes. The credit to the unique use of sequence, series of concentric arches, square chambers and the octagonal base for the dome are to be given to Persian architecture.
What makes Persian domes stand out from the Christian church dome is the use of colourful tiles which were added to the exterior as well as to the interior of the dome as well. The favoured colours of this architecture were gold, white, turquoise patterns on a dark blue background.
