According to the Tesla FindUs there is new Supercharger in Croatia, Europe in construction:
Jastrebarsko, Croatia
45.65361436057305, 15.656770711000238
Cvetković 85a, 10450, Cvetković, Croatia
Most likely 12xV4 - but I have no confirmation for the number of stalls.
It can be inserted either as construction or as plan, we will receive some confirmation most likely in the next days.

This seems to be at the parking lot of Hotel Princess. This is a nice and new hotel which also has a good restaurant.

Anyone close to the place who could make a photo to see if they are really working on the SuC already?
