A  boundary marker, border marker, boundary stone, border stone, boundary tree, 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.

Boundary markers, traditionally, were often made of stone, but later many have been made with concrete or a mixture of materials. They are typically placed at a notable or especially visible point. Many are inscribed with relevant information such as the abbreviation of the boundary holder and often a date.

The phrase boundary marker is all-encompassing, as a boundary stone is a boundary marker, but not all boundary markers are stone. (Also, there are boundary trees.)

How to map

Set a node node and add boundary=marker.

If a boundary marker is historic, one can simply add historic=yes .
