Reja
From Wikipedia, the free encyclopedia
Reja is a Spanish term for grillwork. It typically refers to iron screens, often of a decorative nature.[1]
In medieval times the word was used for ploughshare. It is used in this sense in the Becerro Galicano.
Domestic rejas
Ecclesiastical rejas
Inside cathedrals, fences were often placed in front of side chapels, the choir, or even in rood screens in front of the altar. [1][3] Such rejas are commonly 25 to 30 ft (7.5 to 9 meters) high.[3]

Crafters who made rejas were known as rejeros, or reja-makers.[4]
