The chapel of Notre Dame du Haut in Ronchamp is one of the finest examples of the architecture of Franco-Swiss architect Le Corbusier and one of the most important examples of 20th century religious architecture. It was built between 1953 and 1955. The chapel is a working religious building and attracts 80,000 visitors each year.
Notre Dame du Haut is commonly thought of as a more extreme design of Le Corbusier’s late style. The chapel is a simple design with two entrances, a main altar, and three chapels beneath towers. Although the building is small, it is powerful and complex. The chapel is the latest of chapels at the site. The previous chapel was completely destroyed there during World War II. The previous building was a 4th-century Christian chapel. At the time the new building was being constructed, Corbusier was not exactly interested in “Machine Age” architecture but he felt his style was more primitive and sculptural. Also, he realized when he visited the site that he could not use mechanized means of construction, because access was too difficult.
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.
