The castle of Baone controlled the eastern access to the city of Este, flanked by the castle on Mount Cero and the fortification of Calaone, forming a strategic defensive system. Belonging to the Da Baone family, originally from Padua, it was ceded in 1183 to Marquis Obizzo d'Este. Its history is closely linked to that of the castle of Este, the political center of the marquises.
Built of trachyte stone, the castle included a habitable tower, locked gates, and an internal walkway, surrounded by a vast area cultivated with vines and large walls.
A manuscript preserved at the Civic Library of Padua, possibly attributed to Biasio Lombardo, describes the ruins of the castle and the church of St. Fidenzio. By the 17th century, the site was completely destroyed and transformed into a vineyard.
