The castle of Scaldasole, which probably already existed in the Lombard era, was reconstructed between the 12th and 13th centuries. It reached its current state under the Folperti family at the beginning of the 15th century and is one of the most important castles in the province of Pavia. It comprises a castle to the north and a small sheltered village to the south (three structures joined to the castle with twin towers and a central tower), and it was embellished under the Malaspina family with the addition of a Bramantesco-style portico with arcading.
