Saint-Michel Basilica is a Baroque jewel with its incredible exterior, the bell-tower, the coloured cobbles of the parvis arranged to form the Grimaldi’s coat of arms and the “rampes Saint-Michel” (a series of flights of stairs).
The construction of the Basilica begun in 1640 under the reign of Honoré II, but took several centuries to be completed. The façade was then renovated in the 19th Century adding typical decor of the period such as smooth columns with ionic and corinthian capitals.
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.
