The Fortress of Brunella, perched on the hill overlooking the village of Aulla, is a remarkable example of Renaissance military architecture, possibly with origins dating back to the 13th century and modified over time. Among the most imposing fortifications in Lunigiana, the fortress played a strategic role in controlling the main routes and mountain passes of the Apennines.
Acquired by the Italian State in 1977, it is now owned by the Municipality of Aulla and houses the Museum of Natural History of Lunigiana, which tells the story of the region and its environmental transformations.
