The Castle of Le Castella, which in the past was a complex of walls surrounding a town, was built by Andrea Carafa before 1521, but its origins are even more ancient. In chapter 9 of book 3 of his "Naturalis Historia", Pliny calls it Castra Hannibalis and adds that this fortress is situated in a place called Le Castella because of the several towers characterizing it and looking like castles.
