While the history of Castiglione di Garfagnana has always been linked to its military camp, the town actually dates to Roman times when a primitive Castrum was installed here, which developed in the Longobard and Frankish eras.
In 1806, with the Napoleonic conquests, Castiglione became part of the Lucca Principality. It’s for this reason that the town’s coat of arms bears a lion on a red and white background of the Republic of Lucca. Castiglione was the most important defense fortress of the border with the Duchy of Modena.
