Opening plaques are commemorative markers that celebrate the inauguration of a new building, facility, or public space. They typically feature engraved or printed text, including the date of the opening, the names of key individuals involved in the project, and any relevant organizational or government entities. Opening plaques can be made from materials such as metal, stone, or wood, and are often mounted on a wall, displayed on a stand, or integrated into the architecture or landscaping of the site. They serve as a lasting tribute to the achievement and a historical record for future generations.
