The castle of Suvero was built in the 12th century by the Malaspinadi Villafranca on a hill overlooking the village. During the 15th century it was assigned to the Campofregoso, after Genoa had conquered the territories of the Malaspina. At the behest of King Louis XII, the Genoese returned it to the original owners. After the death of Spinetta Malaspina, lord of Suvero, it became an independent fief assigned to Rinaldo Malaspina, who probably built the castle.
There were then several lords of the Malaspina family: some of them shined for their governmental talent, while others provoked dissatisfaction among the subjects. In 1600 the villagers of Suvero decided then to submit to Spain and to Tuscany, but in the end they always returned under the rule of the Malaspina. After the beginning of the Renaissance the castle lost its defensive function and became definitively a residence. For over 200 years it was the residence of the lords of Suvero and was rarely involved in battles.
The current structure, which probably stands on a pre-existing medieval building, is trapezoidal with three fortified corners and impressive fortified towers. On the western side there is a circular fortified tower. In the 19th century the eastern fortified tower collapsed, and in 1921 the southern one was destroyed by the earthquake. Both have been restored.
References:The Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
