This location is listed on Tesla website as having 4 connectors, up to 14kW. I assume the Tesla destination chargers have been removed since they now have eCarUp chargers, but I'm not able to say for sure with the information on the internet.
On eCarUp, we see 4 clusters with a total of 12 stations. I wonder if there are more, because the numbering isn't very logical. The higher number is 13, but there are duplicate numbers at the various clusters and no 6-9 at all.
Their website mentions charging stations, but not how many. It makes it sound like they are all paid https://www.campofelice.ch/en/services/other-services
E-car station
At Campofelice, you will find several charging stations for electric cars. These operate autonomously: therefore, you are invited to proceed independently. We remind you that it is prohibited to recharge your electric car at the parking spots.
The last paragraph is confusing, I assume they mean you should not charge a car at one of the camping spots using the comping plugs. In German they use the word "Stellplatz".
Based on the information on Chargemap and GoingElectric, it looks like the Tesla chargers used to be in 2 different areas. 2 by the reception, attached to a green stand in front of the hedge, and the other to the south, attached to the wall of a yellow building.
There are no wide pictures of the old chargers in front of the reception, but on Swisstopo satellite images we see the green stand and it looks like there are EV signs painted on the 2 parking spots in front of it.
The yellow building seems to have grass in the parking spots, so it's impossible to spot an EV sign on the ground. In the newer picture of the eCarUp chargers on GoingElectric there's yellow paint at the edge of frame which could be a logo on the parking space.
The newer pictures on GoingElectric for the yellow building show a QR code clearly, which matches with the area called "Casa al porto" on eCarUp. The wall is the same color as the older picture of the Tesla chargers. If we combine this information with this Google Maps picture from August 2018 which seems to be the only wide-ish angle I could find and the 360° pictures from Google Maps as well it seems pretty certain that the Tesla chargers were in the corner to the right of where the eCarUp chargers now are.
All those pictures also show that the parking spots and area around the building were modified through the years. The parking spots used to be asphalt, and there were stairs in the Tesla era that have been replaced with a ramp. In the 360° pictures which are from 2013 as well as this other picture from June 2017 https://maps.app.goo.gl/QnTaPp4yw91gC7qR6 we don't see the correct side of the building but I think we would see the Tesla Wall Connectors on the side if they were installed. They must have been added later.
