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:Kristiansten Fortress was built to protect the city against attack from the east. Construction was finished in 1685. General Johan Caspar von Cicignon, who was chief inspector of kuks fortifications, was responsible for the new town plan of Trondheim after the great fire of 18 April 1681. He also made the plans for the construction of Kristiansten Fortress.
The fortress was built during the period from 1682 to 1684 and strengthened to a complete defence fortification in 1691 by building an advanced post Kristiandsands bastion in the east and in 1695 with the now vanished Møllenberg skanse by the river Nidelven. These fortifications were encircled by a continuous palisade and thereby connected to the fortified city. In 1750 the fortress was modernized with new bastions and casemates to protect against mortar artillery.
