From the outside, Shāh Chérāgh in Shiraz, Iran looks like any other mosque with a detailed exterior. But visitors will likely be surprised by the religious center and funerary monument's dazzling interior. Inside, Shāh Chérāgh is covered in mirrors and glass that give the building a shimmering appearance.
Shāh Chérāgh translates to "King of the Light" in Persian, which is likely a reference to both the building's radiant appearance and its origin story. According to Atlas Obscura, the mosque's story began when a traveler witnessed a strange light around 900 CE. As the man drew closer to the light, he realized it was an illuminated grave holding the armor-clad body of an important Muslim figure. What was once a modest grave then became a luminous mosque and popular pilgrimage site for Shia Muslims.
The structure's internal decorations were created with the intention of refracting light, thanks to an addition during the 14th century by Queen Tash Khātūn, who wanted light to bounce off every corner of the room.
