The town of Molazzana is in the province of Lucca at 474 m of altitude and it has a population of about 1000 inhabitants. Near the chief town, the castle and the church of the saints Lorenzo and Stefano in Cascio and the church of san Frediano in Sassi can be visited.

The first document about Molazzana is to be traced back to a charter of 1105. In this period, the current chief town was within the jurisdiction of the parish of Gallicano, that the rulers of Careggine, first, andthe Porcaresi family, later, dominated. The Republic of Lucca got the territory of Molazzana in 1308 and it decided to split it into two territories that were assigned to the vicariates of Barga and of Camporgiano.
The following century was characterized by the arrival of the Estensi in the territory of Lucca. It was the inhabitants of the area who called them back to put an end to a period of violence and of institutional chaos. Molazzana was first aggregated to the Dukedom of Modena in 1430, but it officially entered the dukedom in 1451, when a diploma by Nicholas V ratified the rise of the Estensi. The territory of the town was united again and entrusted to the vicariate of Trassalico.
During the pontificate of Leo X, who was the son of Lorenzo de' Medici (called "The Magnificent"), Molazzana passed under the domination of Florence. After the Pope died, in 1521, the Dukedom of Modena got possession of the area once again and in 1839 Francesco IV suppressed the town and united it to the town of Castelnuovo. Molazzana recovered its status as a municipality in 1860, thanks to its annexation to the Kingdom of Italy.
Initially, Molazzana entered the province of Massa Carrara and then the province of Lucca in 1923. During the Second World War, the town was one of the most hit during the fights between the Nazi-Fascists and the Anglo-Americans along the Gothic line, a sort of border between the occupied territories and the freed ones, where many massacres and bombardments took place. Fortunately, the ancient fortifications resisted to the violence of war. Today, part of the Fortress of Cascio, built in 1615 by Alfonso III, can still be seen. Two doors, one part of the walls and two towers are still visible. The chief town, too, has preserved some remains of the ancient XV-century castle.
