San Carlo al Corso is a neo-classic church in the center of Milan. The church is managed by the Servite Order.
The church facade was designed in 1844 by Carlo Amati and was finished in 1847. It then served as a model for the Chiesa Rotonda in San Bernardino, Switzerland, 1867.
The complex was built to replace Convent of the Servite founded as early as 1290 and later was suppressed in 1799. The new church was built in thanks for the ending a cholera epidemic, and dedicated to Saint Charles Borromeo who was the Bishop of Milan during the time of the bubonic plague in Milan during the 16th 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.
