This is from Denmark. I think UK and Ireland also have similar looking scenes with those long grasses, sandy beaches and rolling hills. I wonder, though if there's such place somewhere in Southern Europe because it's closer to me. All I've found around the Black Sea and the Mediterranean are more arid landscapes and the grasses aren't as long usually. Obviously I don't expect to get the same architecture, it's more about the grass, sandy beaches and small hills.
Parts of Brittany and Guerande in France, and northwest Portugal look somewhat like this. I think that is the closest you will find.
Maybe geographically closer, but not what one would think of southern.
Actually southern is too arid.
Some of the islands of Croatia might work, Pag comes to mind. Beautiful, windswept in autumn/winter (no people too), known for fantastic sheep cheese. In spring and summer it manages to be hot, humid, and airless.
