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 ancient Argos Theater was built in 320 BC. and is located in Argos, Greece against Larissa Hill. Nearby from this site is Agora, Roman Odeon, and the Baths of Argos. The theater is one of the largest architectural developments in Greece and was renovated in ca 120 AD.
The Hellenistic theater at Argos is cut into the hillside of the Larisa, with 90 steps up a steep incline, forming a narrow rectilinear cavea. Among the largest theaters in Greece, it held about 20,000 spectators and is divided by two landings into three horizontal sections. Staircases further divide the cavea into four cunei, corresponding to the tribes of Argos A high wall was erected to prevent unauthorized access into the theatron and may have helped the acoustics, but it is said the sound quality is still very good today.
Around 120 CE, both theaters were renovated in the Roman style.
