A medallion in construction and interior design is a decorative architectural element, typically circular or oval in shape, used to enhance the aesthetic appeal of ceilings, walls, or floors. Most commonly seen as ceiling medallions, they are installed around light fixtures or chandeliers to add elegance and visual interest to a room. Medallions can be made from materials like plaster, polyurethane, wood, or metal, and come in a variety of styles ranging from classic to modern. While they serve no structural function, medallions are a popular choice for adding ornamental detail to interior spaces.
