The Broletto or Broletto Palace of Brescia has for centuries housed the civic government offices of the city. Initial construction of the Broletto took place during 1187—1230, although the structure has undergone many modifications over the centuries, specially after the Sack of Brescia in 1512 during the War of the League of Cambrai.
The long stone facade on the south fronts Via Cardinale Querini and aligns parallel the left of the Cathedral. The nearly 54 meter Tower of Pègol is still intact, with a small belfry hidden by the Ghibelline crenellations added at the beginning of the 19th century.
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.
