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:
Hluboká Castle (Schloss Frauenberg) is considered one of the most beautiful castles in the Czech Republic. In the second half of the 13th century, a Gothic castle was built at the site. During its history, the castle was rebuilt several times. It was first expanded during the Renaissance period, then rebuilt into a Baroque castle at the order of Adam Franz von Schwarzenberg in the beginning of the 18th century. It reached its current appearance during the 19th century, when Johann Adolf II von Schwarzenberg ordered the reconstruction of the castle in the romantic style of England's Windsor Castle.
The Schwarzenbergs lived in Hluboká until the end of 1939, when the last owner (Adolph Schwarzenberg) emigrated overseas to escape from the Nazis. The Schwarzenbergs lost all of their Czech property through a special legislative Act, the Lex Schwarzenberg, in 1947.
The original royal castle of Přemysl Otakar II from the second half of the 13th century was rebuilt at the end of the 16th century by the Lords of Hradec. It received its present appearance under Count Jan Adam of Schwarzenberg. According to the English Windsor example, architects Franz Beer and F. Deworetzky built a Romantic Neo-Gothic chateau, surrounded by a 1.9 square kilometres English park here in the years 1841 to 1871. In 1940, the castle was seized from the last owner, Adolph Schwarzenberg by the Gestapo and confiscated by the government of Czechoslovakia after the end of World War II. The castle is open to public. There is a winter garden and riding-hall where the Southern Bohemian gallery exhibitions have been housed since 1956.
