The oldest part of the Masnago castle is an 11th-century crenellated tower. The current appearance is result of a series of modifications and extensions from the Middle Ages (11th – 13th centuries) to the 18th century, is one of the most important historical buildings in Varese. The main body of the castle dates from the 15th century and gave the castle the appearance of a mansion house, as may be seen from the façade overlooking the Mantegazza Park. Finally, the wing that was built into the pre-existing medieval fortress in the late 17th – early 18th centuries resulted in its present appearance as a country residence.
The Castiglioni family, who owned the Castle from the 15th to the beginning of the 20th century, were responsible for the exquisite frescoes. On the death of Marquis Paolo Castiglioni Stampa the castle was inherited by a female branch of the family, and was later sold to Angelo Mantegazza of Varese.
The frescoes, painted in the style known as International Gothic, date to around the mid-15th century, but were discovered only in 1938. Two of the interior rooms are frescoed: the Sala degli Svaghi (the “Pastime Room”) where the pastimes of the court are depicted, and the Sala dei Vizi e Virtù (“Room of Vices and Virtues”) illustrating the morals of the time.
The Castle’s magnificent rooms also host the Museum of modern and contemporary art.
References:Sigmaringen Castle was first mentioned in the year 1077 in the chronicles of Petershausen monastery. The oldest parts of the castle are concealed beneath the alterations made during the 17th and the 19th centuries. The secret of the earliest settlement built on this defendable rock will never be fully revealed: large-scale excavation work would be necessary, which the extensive land development renders impossible. Judging from the many Roman remains unearthed in the area around Sigmaringen, the 12th century keep known as the 'Roman Tower' could be traced back to a Roman predecessor.
The castle remains that have been preserved (gate, great hall and keep) date back to the Staufer period around 1200. The castle remains were integrated into subsequent buildings. The foundations of the castle buildings are to a large extent identical to the surrounding castle wall.
These remains give us a good idea of how the castle might have looked during the 12th century.
