The Drugolo castle is located in the village with same name along the road that leads from Padenghe to Bedizzole in the morainic hills. Its construction is dated to the 10th century, perhaps by the Lombards.
It has a square plan with two corner towers and is positioned on a wall that raises it considerably, has a drawbridge and Ghibelline battlements; towards the end of the 14th century the perimeter walls were rebuilt. In its history it was owned by the Vimercati of Milan until 1436, then passed to the Averoldi of Brescia until 1935, the Lanciani Rocca and now the barons Lanni della Quara.
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.
