Born from a project promoted, financed and coordinated by the Ministry of Culture in agreement with the local authorities of the territories involved, it has as its main objective the valorization and promotion of the territory between Emilia-Romagna and Garfagnana, which from the 14th to the 19th century was part, with alternating fortunes, of the Estense State, the longest-lived and most extensive Italian territory dominated, without interruption, by the same dynasty.
