24-Jul-2018 -- While driving from Lyon westward to Clermont-Ferrand, I made a short detour to visit this fascinating Degree Confluence Point, What makes this point fascinating is that it lies just inside the grounds of a (privately-owned) chateau - “Le Château de la Grange à Lapeyrouse”.
The point itself lies on the edge of an open field, in front of the chateau. Just to the south is a rural road; from there, I launched my drone to get aerial views from more than 100 m up.
Here is a remote-controlled aerial video of this confluence point.
