A reja ("grille") is a decorative screen of iron.[1]
Rejas can be found in cathedrals located in Spain and Portugal.[1][2] Inside the cathedrals, rejas were often placed in front of side chapels, the choir, or even in rood screens in front of the altar.[1] Rejas are commonly 25 to 30 ft (7.5 to 9 meters) high.[2] Crafters who made rejas were known as rejeros, or reja-makers.[3]
