Castelnuovo is considered both the capital and the green heart of the Garfagnana. It is located in the area to the north of the river Serchio, between the Apennines and the Apuan Alps, about forty kilometres from the city of Lucca. The schools, the library and the beautiful Teatro Vittorio Alfieri are just some of the elements that make this little town a cultural centre for the whole territory.
Among the many historic governors of the area, the standout character is the poet Ludovico Ariosto, who was sent here between 1522 and 1525 to oversee the Este family's share of the Garfagnana. He gave his name to the local fortress, which remains Castelnuovo's main attraction.
