surveyor's monument

A surveyor's monument is a physical marker placed by land surveyors to define key reference points on the property boundary or land survey. These markers can be made of various materials like capped pipes, stones, concrete posts, or metal rods, and are often embedded into the ground or affixed to structures. They serve as permanent, precise indicators used to establish or verify property lines, boundary corners, or specific land features, ensuring legal clarity and consistent land records. These monuments are essential in property delineation, construction, and land development projects.
