Dear pabluzzo,
Thanks for submitting this note.
The climbing hall is tagged with leisure=sports_centre and sport=climbing. I believe that's correct, and it's consistent with other climbing halls in the area, e.g. https://osm.org/node/5020872971 and https://osm.org/node/2905963843.
Therefore I'm closing this note. Feel free to reopen it if you feel I misunderstood.
