Photo from Pierre’s instagram
Pierre-Antoine posted a photo on instagram saying “Ce soir c est l Alta rocca” (in English : “tonight it’s the Alta Rocca”, “l’Alta Rocca” is Corsican name meaning “the high mountain”).
I believe it could refer to the micro region called “l’Alta rocca” in Southern Corsica (not very far from Ajaccio). It’s possible that they are visiting over there.
Some info it : l’Alta rocca
