The Benedictine Convent of St John at Müstair, located in a valley of the Grisons in the extreme south-eastern part of Switzerland, south of the Alps, was founded around 775, probably on the orders of Charlemagne. At the beginning of the 9th century it was noted as being an establishment of religious Benedictines, and became a women’s abbey in the first half of the 12th century. Religious activities have continued uninterrupted until the present day, with the abbey becoming a priory in 1810. Today, the convent ensemble comprises the Carolingian conventual church and the Saint Cross Church, the residential tower of the Abbess von Planta, the ancient residence of the bishop, including two rectangular courtyards. To the west the courtyard is surrounded by cloisters, two entrance towers and agricultural buildings.
The property reflects both the history of its construction and the political and socio-economic relations in this region and throughout Europe over more than 1200 years, and thus provides a coherent example of Carolingian conventual architecture over time.
The conventual church houses the most important cycle of frescoes of the Carolingian era conserved in situ. The creation of these frescoes is dated around the first half of the 9th century. The church, which is conserved for the most part in its Carolingian style, was initially destined as a space to be decorated with paintings: representations of the history of Christ decorate its entire perimeter, the apses and the inner walls. The scenes are laid out in a decorative way with elements connected by thematic and spatial correspondence and represent an outstanding example of Christian iconography.
By reason of its exceptionally well-preserved heritage of Carolingian art, it has been a UNESCO World Heritage Site since 1983.References:
The Château de Chaumont was founded in the 10th century by Odo I, Count of Blois. The purpose was to protect his lands from attacks from his feudal rivals, Fulk Nerra, Count of Anjou. On his behalf the Norman Gelduin received it, improved it and held it as his own. His great-niece Denise de Fougère, having married Sulpice d'Amboise, passed the château into the Amboise family for five centuries.
Pierre d'Amboise unsuccessfully rebelled against King Louis XI and his property was confiscated, and the castle was dismantled on royal order in 1465. It was later rebuilt by Charles I d'Amboise from 1465–1475 and then finished by his son, Charles II d'Amboise de Chaumont from 1498–1510, with help from his uncle, Cardinal Georges d'Amboise; some Renaissance features were to be seen in buildings that retained their overall medieval appearance. The château was acquired by Catherine de Medici in 1550. There she entertained numerous astrologers, among them Nostradamus. When her husband, Henry II, died in 1559 she forced his mistress, Diane de Poitiers, to exchange Château de Chaumont for Château de Chenonceau which Henry had given to de Poitiers. Diane de Poitiers only lived at Chaumont for a short while.
Later Chaumont has changed hands several times. Paul de Beauvilliers bought the château in 1699, modernized some of its interiors and decorated it with sufficient grandeur to house the duc d'Anjou on his way to become king of Spain in 1700. Monsieur Bertin demolished the north wing to open the house towards the river view in the modern fashion.
In 1750, Jacques-Donatien Le Ray purchased the castle as a country home where he established a glassmaking and pottery factory. He was considered the French "Father of the American Revolution" because he loved America. However, in 1789, the new French Revolutionary Government seized Le Ray's assets, including his beloved Château de Chaumont.
The castle has been classified as a Monument historique since 1840 by the French Ministry of Culture. The Château de Chaumont is currently a museum and every year hosts a Garden Festival from April to October where contemporary garden designers display their work in an English-style garden.
