There's a Chargemap marker for this location which I had not noticed before, called "Hotel Silvana".
It's marked out of service and only has two comments, someone saying they charged with Swisscharge in March 2017 and someone saying the charger is out of service and electricity has been cut in May 2018.
The pictures show an Energie360 charger with a green parking spot in front of the building. The data lists a Type2 connector and also a Schuko, not sure if those were on the same charger. It could have been on that model of charger.
Since I didn't know about it, I had not planned to stop here, but I happened to capture the corner that once hosted the charger when photographing the Bruenig Lodge which is right next to it. We see remnants of green paint on the floor but the charger is gone.
The charger seems to have already been gone when opendata started operating at the end of 2019, I don't have any information on this location in my archives. One of the Chargemap pictures show the sticker with the charger ID but it's low quality and hard to read. To me the text looks like 2493, but I was able to scan the QR code just briefly and it gave me 2491, but I was not able to read it a second time with Google Lens. I was able to download a higher resolution version, it's clearly 2491.
I don't think the hotel the charger was named after still exists, but it's really hard to say because I don't find any article about its closure, only old websites that still offer to book a room here. On Google Maps there's a new restaurant name but I didn't take any picture of the front of the building to see what is still advertised.
