Luxurious residence in neo-Gothic style, built as a summer residence in 1887 by senator Giacinto Guglielmi and his wife Isabella, incorporating the fourteenth-century Franciscan convent and the church of San Francesco.

For many decades of the 20th century, many Italian nobles were attracted to this building and its large lush park on the lakeshore. The rooms of the castle were richly furnished: art collections, including exotic ones, ancient coins, shells of all shapes and sizes, the gallery with portraits of ancestors and armours (especially Japanese), the party room with Murano chandeliers and the large billiard table much used to give amusement and entertainment during the frequent social evenings.

To date, the complex – in decline since the 1970s – is privately owned.
