Hello!

What you wanted to map by mapping https://www.openstreetmap.org/way/1264864584 ?

It looks like building is visible here on aerial imagery but it was marked as "beacon".

It has "Batiment" meaning (from what I checked) "building" in French.

Have you wanted to map it as a building?

If yes - can you edit it to match better its shape visible on aerial imagery?

Feel free to ask for help if you need it! Note that it much better to draw 1 accurate building than 1000 badly drawn ones.
