Solza Castle probably dates back to the 10th or 11th century. Here was born the famous condottiere Bartolomeo Colleoni. According to tradition, when Bartolomeo Colleoni left Solza Castle, he was between 14 and 15 years old: little more than a boy, even for those times. No-one could have predicted then that he was destined to become one of the most famous condottieri of the fifteenth century.
Today the same castle appears rather insignificant with its modest fourteenth century plan, but it is still worth visiting the small village of Solza, near the river Adda, and use it as starting point for making a historical tour of the castles dotted over the Bergamo plain. Two great powers, the Duchy of Milan and the Republic of Venice, were long-term rivals in this border country.
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.
