Grave markers, also known as headstones or tombstones, are objects placed at the head of a grave to identify the deceased. They often display important information such as the person's name, birth date, and death date. Grave markers can be made from various materials, including granite, marble, and bronze, and come in different shapes and sizes. In addition to basic information, grave markers may also include symbols or inscriptions that reflect the individual's life, beliefs, or interests. Some families choose to personalize these markers with photos, quotes, or decorative elements, making each one unique and meaningful to those who visit the grave.
