Commemorative plaque

A commemorative plaque, or simply plaque, is a plate made of metal, ceramic, stone, wood, or other material. It is usually placed on a wall or a large stone. It usually has text and sometimes an image in memory of one or more persons, as used for epitaph, an event, a former use of the place, or some other thing. A plaquette is a small plaque. The word plaquette is not usually used for outdoor plaques fixed to wall.
