Rejas

Rejas are metal bars or grills used as protective or decorative elements in architecture and design. They are typically constructed from wrought iron or steel and installed on windows, doors, balconies, courtyards, and staircases. Rejas serve to deter intrusion while allowing light and air to pass; they also function as ornamental elements, with designs ranging from simple straight bars to intricate scrollwork and finials. The term is common in Spanish-speaking countries; in Iberia and Latin America, rejas are found in both historic heritage buildings and modern constructions, reflecting a long tradition of metalwork in Spanish architecture.

In architectural practice, rejas can be fixed to structural openings with anchors or set into frames. In residential settings, they provide security without entirely obstructing visibility or ventilation. In religious and institutional architecture, metal screens called rejas have been used to separate sacred spaces, choir lofts, or altars from the nave, as well as to protect chapels. During the 16th to 19th centuries, various stylistic influences—such as Moorish, Renaissance, and Baroque—shaped reja motifs, resulting in decorative patterns and cresting that enhanced their visual presence.

Today, rejas continue to be produced by metal artisans and installed for both functional security and stylistic purposes. Maintenance typically involves protection against rust, periodic repainting, and checks for loose fasteners. Rejas remain a recognizable element of regional architectural identity in many Spanish-speaking communities.
