Lunigiana is an historical region between Tuscany , Liguria and Emilia that has a very definite personality . The wayfairing along the Via Francigena that exploits its morphology as a natural corridor between these areas has conditioned both the history and the organization of the territory . Furthermore , the absence of cities has favoured the development of feudal dominions and the building of a great number of castles and fortified medieval villages that are nearly all still standing today .
