Windmill World Map

About Windmill World Map 🌬️

Windmill World Map marks the windmills of the world — working mills still turning, restored landmarks and the tower stumps that remember an age of wind-powered grinding and pumping.

Each windmill comes from OpenStreetMap's `man_made=windmill` tag and is kept current by mappers and heritage enthusiasts. Many are private or open only on set days, so check before you visit.

Who is behind this site?

Windmill World Map is built and maintained by Emil Björk, an independent developer based in Sweden. The site grew out of a passion for maps, travel and open data, alongside a professional background in IT consulting.

How it works

Every point is fetched from the OpenStreetMap Overpass API, deduplicated, tagged by country and stored as a static GeoJSON file — no database, instant to load. Click any point to see a description from Wikipedia, a photo from Wikimedia Commons (or Mapillary as a fallback) and, where available, its Google rating.

Data freshness

The dataset is automatically refreshed once a month from OpenStreetMap via a scheduled GitHub Action, so the map stays current as the world is mapped.

Spot something missing?

This map is only as complete as OpenStreetMap itself. If you know a windmills that isn't here, you can add it directly to OpenStreetMap — it's free, open and will appear here at the next refresh.

New to OpenStreetMap? See the how-to-tag guide for windmills. Edits show up here at the next monthly refresh.

Report an error or a wrong location

Found a windmills in the wrong spot, with outdated details, or listed twice? The data lives in OpenStreetMap, so the quickest fix is a short note there — a local mapper reviews it and the correction flows back to this map at the next refresh.
