This beautiful building is often nicknamed Pink Mosque for two reasons. The Nasir al Mulk mosque was built in the center of Iran’s Shiraz, where the conditions for growing roses are excellent so there really are many. Another reason is the pink mosaic tile, which is supposed to resemble the sunrise and sunset. Perhaps the most beautiful is the interior windows, which contain colorful stained glass. Each of them is decorated with the completely different motif. The most impressive are the windows on the east side. If you plan your visit properly and arrive here in the morning just after sunrise, you will be able to admire the beautiful splashes of colors and lights on the walls of the mosque.. 

Colorful stained glass are the dominant feature of the Pink Mosque

Best time for visitng the mosque is in the morning for the light
