Nasir al Mulk Mosque, Shiraz, Iran

Built in 1876 to 1888, the mosque is known as the Pink Mosque or the Colorful Mosque. It is perhaps best known for the use of stained glass windows in the prayer hall, unusual in a Muslim building, and for the riotous effects created by the colored light spilling across colored carpets and tiles. Perhaps not the most meditative decoration scheme, but certainly spectacular.
