A stone or post set at the corner of a building, gateway or wall, or at the edge of a road or bridge, to protect the structure from damage by the wheels and hubs of passing vehicles, common from Roman times through the age of horse-drawn traffic and often surviving as heritage features, sometimes decorated or made from reused cannon; guard stones are related to bollards and to kerb and wheel guards in modern traffic design.
