The Castello di Montesegaleis a rural hilltop medieval fortress. It was originally built in the 14th century but over the next centuries was destroyed and rebuilt. An earlier 11th-century tower may have existed at the site.
Documents from 1164 indicate that Emperor Federico Barbarossa conceded a castle or fortress at Montesegale to Pavia. The property was owned by the Count Gambarana by 1311, who became the lord of Montesegale. In 1415, in retribution for a rebellion against Filippo Maria Visconti, his general Carmagnola captured and destroyed the castle. Count Guido Gambarana was captured, tortured, and executed. In 1451, Palatine Count Ottino Gambarana, the son of Guido, obtained from Duke Francesco Sforza restoration of his feudal inheritance. The position of the counts of Montesegale was confirmed by Emperor Charles V in 1525. The property passed on the Giussani family in 19th century, and then to the Jannuzzelli family.
The castle has outer walls and an inner walled keep. The interior walls were restored in 1900 by Agostino Gambarotta. The portal to the inner courtyard has a Latin epigraph that reads Fiat pax in virtute tua et habondantia in turribus tuis ('May there be peace in your strength and prosperity within your towers'). The castle portico has heraldic shields of the Gambarana family.
In 1975, the castle became the site of the local museum of contemporary art.
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.
