A plaque is a flat, typically rectangular piece of material, often made of metal, wood, or stone, that serves as a memorial or commemorative marker. It usually features inscriptions that honor a person, event, or place, providing information about its significance. Plaques can be found in various locations, such as parks, buildings, and historical sites. Memorial plaques are often used to commemorate individuals, such as veterans or cultural figures, and can also mark important events, like anniversaries or historical milestones. They serve as a way to preserve memory and educate the public about the contributions or events they represent.
