When it comes to historical buildings, we usually imagine castles, towers, bricks and mortar. Rarely do we think about the colors it might have. Here's an exception. The Nasir Al-Molk Mosque was built in 1876 in Shiraz, Iran. The specialized stained glass windows were built to capture the morning light and create a glorious and colorful display of light on the building's floor, earning it the name "Pink Mosque".
At certain times of the day, it seems like this building contains all the colors in the world. It also uses traditional Islamic architecture styles, such as iwan arches, a central fountain and others. However, the stained glass windows are a rarity in mosques, with another example being the famous blue mosque in Istanbul.
