The castle of Vigolo was erected during the Renaissance in a strategic position over the pass between Vigolana and Marzola, in order to defend the town. The first record of castle dates back to 1214. In 1254 it was besieged and destroyed.
In 1424 the castle passed to the family of Murlini and later in 1477 to de Fatis, whose descendants are still the owners. The de Fatis acquired the castle in ruins and rebuilt it almost completely in the 16th century style, turning it into an aristocratic residence country. These changes appears today. Being a private home, the castle is not open to the public.
References:Sigmaringen Castle was first mentioned in the year 1077 in the chronicles of Petershausen monastery. The oldest parts of the castle are concealed beneath the alterations made during the 17th and the 19th centuries. The secret of the earliest settlement built on this defendable rock will never be fully revealed: large-scale excavation work would be necessary, which the extensive land development renders impossible. Judging from the many Roman remains unearthed in the area around Sigmaringen, the 12th century keep known as the 'Roman Tower' could be traced back to a Roman predecessor.
The castle remains that have been preserved (gate, great hall and keep) date back to the Staufer period around 1200. The castle remains were integrated into subsequent buildings. The foundations of the castle buildings are to a large extent identical to the surrounding castle wall.
These remains give us a good idea of how the castle might have looked during the 12th century.
