Oppenheimer filming locations in Switzerland

[Alectruffa]

So I've just come back from a psychedelic trip through history with Oppenheimer. The film was fraught with too many pieces of a complicated jigsaw puzzle that finally made a bit of sense at the end but that is beside the point.

In the first ten minutes, Oppenheimer has visions of quantum science in his head and I swear I saw the Rigi Hochfluh straddling above the clouds and a quick shot of the Einsiedeln monastary.

I did find one source that listed Switzerland among the various filming locations but I was just wondering if anyone else caught a glimpse of the above as well.
