Occupied by Lucca in 1170, during the wars against the confederations of families in Garfagnana, the rocca of Ceserana assumed the role of main garrison in the 'Vicaria delle Terre Nuove' among other military garrisons controlling this recently conquered territory. The place played an important role during the wars of the XIIIth and XIVth centuries and in 1401 was listed by Paolo Guinigi among the outposts that needed to be properly fortified.
With the inclusion of Ceserana in the territory of the Dukes of Este, grand fortification works on the rocca began and lasted from 1467 to 1474. Successively it became the nest of bandits and was left to decay. The conditions of the fortifications must have been appalling on the eve of the war between Modena and Lucca, in 1614, if we trust the description made by the keeper Orazio Caselli.
The Duke of Este entrusted the architect Pasio Pasi with the reinforcement of the rocca; his intervention was more necessary than ever since Lucca had built, in the neighbouring village of Lupinaia, a tower that with its height directly menaced from above the village of Ceserana. Pasi's project was interrupted with the end of the war and only partially achieved in one of the two massive semicircular towers equipped with gunports.
