Puy de Dôme is a lava dome in central France (just west of Lyon). In 2018, it was established as a UNESCO World Heritage site.
This image is from a hill in what is now Royat. Information about the village of Royat is at: https://www.royat.fr/
The large building at the left of this postcard is now the Saint Leger's Church of Royat. It is shown in the image below, that was taken on March 16, 2020 from Google Maps: https://www.google.com/maps/@45.7646464,3.0493268,3a,75y,89.89h,96.7t/data=!3m6!1e1!3m4!1sZbmyAITkY5HBquyQj-coXg!2e0!7i13312!8i6656
This postcard is very difficult to read. *Thank you to KR for making this part out: "... Long live God! Good-bye".
The initials look like "FK". Is it possible that this is a card from Reverend Father Kockerols?
