A commemorative plaque is a flat, often engraved marker that honors a person, event, or place. These plaques are typically made from materials like metal, stone, or ceramic and are installed in public spaces, buildings, or monuments. They serve to recognize significant contributions or historical moments, making them a part of cultural heritage. Commemorative plaques can be found in various locations, such as parks, museums, and historical sites. They often include inscriptions that provide information about the subject being honored, such as notable figures like Martin Luther King Jr. or events like World War II.
