This photo shows the ceiling of one of the iwans or arches of Vakil Mosque in Shiraz. The intricate Islamic architecture, beautiful muqarnas, and seven-color tilework reflect the distinctive style of the Zand era. It appears to be taken from the ceiling of the entrance to the prayer hall or one of the main arches, where the mosque’s famous stone columns and elegant geometric patterns and Islamic calligraphy are prominently displayed.
