Hey Piagno. Thank you for your comment. Acording to official maps, only the bus stop on the main road exists. I can't remember if its an old bus stop or only wrong located. The POI should be deleted.

Sorry, da ist die Haus-Nummer ins falsch Feld geraten. Das Gebäude ist in der Gemeinde Fläsch (also 7306). Bei der PLZ im Kanton GR orientiere ich mich jeweils nach der Gebäudeadressierungs-Karte auf edit.geo.gr.ch. Danke für den Hinweis.

Thank you for your observation. I tried to map systematically all the buildings of Wildhaus with the aerial photo and the adresses after the Amtliche Vermessung from the Canton of St.Gallen. The "building" you are talking about has the offical adress Dorf 4 (see https://www.geoportal.ch/ktsg/map/40?y=2744760.33&x=1229774.56&scale=500&rotation=0 ). It's a long time ago I was in Wildhaus, so your local knowledge is very likely better. Feel free to improve Openstreetmap to the best of one's knowledge and belief.
