This map image could be re-created using vector graphics as an SVG file. This has several advantages; see Commons:Media for cleanup for more information. If an SVG form of this image is available, please upload it and afterwards replace this template with {{vector version available|new image name}}.
It is recommended to name the SVG file “Luxembourg2022OSM.svg”—then the template Vector version available (or Vva) does not need the new image name parameter.
Summary
DescriptionLuxembourg2022OSM.png
English: This map of Luxembourg shows the country's cities, towns, villages and some other geographical details, and is likely the most comprehensive map of the country in this respect that you'll find anywhere online. It has been stitched together from panels of Open Street Map (which is freely licensed to all) with neighbouring countries darkened slightly by the uploader to make the subject country show up somewhat more clearly. Areas in the neighbouring countries include the main towns/cities therein (Arlon, Trier, Thionville, etc.).
