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:
The famous Italian Medici family have given two queens to France: Catherine, the spouse of Henry II, and Marie, widow of Henry IV, who built the current Luxembourg palace. Maria di Medici had never been happy at the Louvre, still semi-medieval, where the fickle king, did not hesitate to receive his mistresses. The death of Henry IV, assassinated in 1610, left the way open for Marie's project. When she became regent, she was able to give special attention to the construction of an imposing modern residence that would be reminiscent of the Palazzo Pitti and the Boboli Gardens in Florence, where she grew up. The development of the 25-hectare park, which was to serve as a jewel-case for the palace, began immediately.
The architect, Salomon de Brosse, began the work in 1615. Only 16 years later was the palace was completed. Palace of Luxembourg affords a transition between the Renaissance and the Classical period.
In 1750, the Director of the King's Buildings installed in the wing the first public art-gallery in France, in which French and foreign canvases of the royal collections are shown. The Count of Provence and future Louis XVIII, who was living in Petit Luxembourg, had this gallery closed in 1780: leaving to emigrate, he fled from the palace in June 1791.
During the French Revolution the palace was first abandoned and then moved as a national prison. After that it was the seat of the French Directory, and in 1799, the home of the Sénat conservateur and the first residence of Napoleon Bonaparte, as First Consul of the French Republic. The old apartments of Maria di Medici were altered. The floor, which the 80 senators only occupied in 1804, was built in the middle of the present Conference Hall.
Beginning in 1835 the architect Alphonse de Gisors added a new garden wing parallel to the old corps de logis, replicating the look of the original 17th-century facade so precisely that it is difficult to distinguish at first glance the old from the new. The new senate chamber was located in what would have been the courtyard area in-between.
The new wing included a library (bibliothèque) with a cycle of paintings (1845–1847) by Eugène Delacroix. In the 1850s, at the request of Emperor Napoleon III, Gisors created the highly decorated Salle des Conférences, which influenced the nature of subsequent official interiors of the Second Empire, including those of the Palais Garnier.
During the German occupation of Paris (1940–1944), Hermann Göring took over the palace as the headquarters of the Luftwaffe in France, taking for himself a sumptuous suite of rooms to accommodate his visits to the French capital. Since 1958 the Luxembourg palace has been the seat of the French Senate of the Fifth Republic.
