The Castiglione del Terziere castle, in the municipality of Bagnone, is historically important, formerly known as “dei Corbellari”, referring to the noble consort of families to which the Este family had sub-infeuded the territory.
In 1275, the castle was renamed “del Terziere” when it was added as the “third part” of the feudal inheritance of Marquis Alberto Malaspina of Filattiera (Spino Fiorito branch). Commanded by the Florentine Captain of Justice from 1451 onwards, it was with Fivizzano an important administrative center subject to Florentine ruling.
Today the castle is a private holding, and following extensive and authentic restoration work, is home to the Niccolò V Center of Humanistic Studies and the Libera Cattedra di Filologia e Polifonia Vocale. as well as an archive and library preserving important texts. The archive and library hold ancient and valuable volumes.
