“Switzerland, 1969”, but where exactly?

Hello together. A family friend has sent this picture to me: “Hey dry_yer_eyes. I took this photo in Switzerland in 1969 but can’t remember where. You live there, so can you tell me where it is?”

The only thing I have to go on is he speaks German, so it’s slightly more likely to be from a German-speaking location than otherwise.

Can anyone recognise the town?
