Volta Mantovana Castle was mentioned in a deed of donation of the same to the bishop of Mantua by Beatrice Canossa in 1055. From other documents of the time, we learn that the fortification consisted of two parts, one inside and one outside the castle keep and oval , composed by a wall of pebbles and bricks about five meters high, this opened some gates and was surrounded by a moat.
From the 11th to the 14th century it was an important link in the chain of fortifications of the territories of high Mantua and, given the frequent conflicts with neighboring the Scala family, was added by the Gonzaga a second outer walls to protect even the village and the Romanesque church. It also served as a shelter for the grain grown in the area, as proof of this, in 1468 the vicar asked permission to the Marquis Gonzaga to distribute to the people of Cavriana Goito and a part of the same.
During the 15th century the Gonzaga will make building inside the fort a summer residence, what is now Palace Gonzaga – Cavriani, built close to the keep reusing part of murra boundary. In later centuries the fort was damaged either during the passage of the troops of Emperor Ferdinand II and during the independence wars of the nineteenth century. The fortifications and the castle Volta Mantovana to date remain well preserved parts of the city to the south and west of the village, other parts incorporated in homes east, while to the north the original boundary wall and a tower have been incorporated in Palace Gonzaga – Cavriani.
References:Rosenborg Palace was built in the period 1606-34 as Christian IV’s summerhouse just outside the ramparts of Copenhagen. Christian IV was very fond of the palace and often stayed at the castle when he resided in Copenhagen, and it was here that he died in 1648. After his death, the palace passed to his son King Frederik III, who together with his queen, Sophie Amalie, carried out several types of modernisation.
The last king who used the place as a residence was Frederik IV, and around 1720, Rosenborg was abandoned in favor of Frederiksborg Palace.Through the 1700s, considerable art treasures were collected at Rosenborg Castle, among other things items from the estates of deceased royalty and from Christiansborg after the fire there in 1794.
Soon the idea of a museum arose, and that was realised in 1833, which is The Royal Danish Collection’s official year of establishment.
