Gravestone preservation involves the techniques and practices used to maintain and protect gravestones and monuments from deterioration. This process often includes cleaning, repairing, and stabilizing stones to prevent further damage from environmental factors like weather, pollution, and biological growth. Preservation efforts may also involve documenting the gravestones, which can help in historical research and genealogy. Organizations and volunteers often work together to restore and maintain cemeteries, ensuring that the legacies of individuals, such as veterans or historical figures, are honored and remembered for future generations.
