The tag barrier=wall is used to map a wall: a freestanding structure, designed to restrict or prevent movement across a boundary, typically made from solid brick, concrete or rocks, and almost always built so that it is opaque (cannot be seen through).

Also see barrier=fence for fences, barrier=retaining_wall for retaining walls, and barrier=city_wall for town walls.

How to map

Create a line way (way) and add the tag barrier=wall

Additional tags

  • wall=* is used to describe the principle feature of the wall, which might be the type, purpose, or building material of the wall
  • height=* is used to specify how tall the wall is.
  • width=* is used to specify the thickness of the wall. Alternatively, use est_width=* to specify approximately how thick the wall is.
  • material=* is used to define the material the wall is constructed of: stone, brick, concrete, wood, etc.
  • colour=* is used to define the colour of the wall

For historic walls the tag historic=wall can be used. If it is under preservation see heritage=*.

Mapping as an area

It is also possible to map a wall as an area area. Then draw the basic area of the wall and add area=yes.

Further tagging

There are situations a wall is on top of a building or another wall - e.g. noise protection wall on top of a building. Then use key min_height=* for the start height of the wall.

The construction material can also be tagged with material=*, if necessary, using values like stone, brick, concrete, or wood.

See wall=no for tagging of open buildings from an import in France.
