The bastion of Riva del Garda is one of the icons of the town. Built on the Rocchetta mountain it is easily reachable in 15-20 minutes walking along a paved road. The bastion was built at the beginning of the 16th century to protect the town as well as its inhabitants right after the Venetian domination of Riva had come to an end. The building was destroyed in 1703 by the French troops under the command of General Vendôme.
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.
