On the left side of the Taverne stream, in the Municipality of Licciana Nardi, you’ll find the hamlet of Pontebosio. Its name was derived from the presence of an ancient bridge that was named for Boso or Bosio. He was part of a noble family that lived in the hamlet of Verrucola, near Fivizzano. The town’s square hosts a castle, constructed in the seventeenth century. Throughout its history, the castle has had many functions; it has been a noble residence, a seminary and a middle school. Judging by its architectural elements, the castle was most likely a military structure in the past. The town’s Baroque style parish church was built by Ferdinando Malaspina as a substitute for the old oratory. Nearby, visitors will also find the Poderetto Castle, built by the Malaspina of Podenzana. Leaving from the hamlet, if you pass under the ‘Vota’ (vault), you’ll find an ancient mill which is currently not active. Alongside the river, you’ll also find the remains of a paper mill.
