A boundary marker, border marker, boundary stone, or border stone is a robust physical marker that identifies the start of a land boundary or the change in a boundary, especially a change in direction of a boundary.[1] There are several other types of named border markers, known as boundary trees,[2][3] pillars, monuments, obelisks, and corners.[1] Border markers can also be markers through which a border line runs in a straight line to determine that border.[1] They can also be the markers from which a border marker has been fixed.[1]
