A traditional windmill, largely constructed from wood or brick/stone. Historically often used to mill grain using wind power.

For a modern Wind turbine use power=generator + generator:source=wind instead.

How to map

Add a node at the centre of the windmill, or draw its outline as an area . Add the tag building=windmill.

Tags used in combination

• name=* - Many historical windmills are named individually.
• man_made=windmill - Smock and tower mills are also buildings. In these cases it can be appropriate to put all tags on the outline.
• windmill:type=post/tower/smock - indicate whether it's a Post mill, a Tower mill or a Smock mill
• functional=yes/no - Is the windmill still fully functional? Can it still mill grain (or whatever it was used for), even if it's really been out of service for years?
• windmill:disused=yes - Mill equipment is out of service. The building can also be used for other purposes, for example, living, cafe, exhibition
• abandoned:man_made=windmill - submitted by the owner and no longer serviced
• ruins=yes - if it is a ruin
• windmill:vanes=yes/no if the windmill vanes (or sails) still exists
• mock=yes if it is a mock mill (a fake, or dummy) which never contained any machinery.
• access=* - Is it possible for the general public to enter it, even if only occasionally?
• start_date=* - When was it built?
• wikipedia=* - reference to possible Wikipedia article
• wikidata=* - reference to possible wikidata item for the windmill
• Addresses
• contact=*

If a other features such as a cafe or gift shop are in the same building, add separate node(s) with corresponding tags. See One feature, one OSM element.
