Thanks to Joanna, I finally have a card from this swiss UNESCO site. To have all the swiss sites, I'm only missing a card with a Le Corbusier work.
The Convent of Müstair, which stands in a valley in the Grisons, in the extreme south-eastern part of Switzerland, is a UNESCO WHS since 1983.

It 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 ensemble is one of the most coherent architectural works of the Carolingian period and High Middle Ages, with the most extensive cycle of known paintings for the first half of the 9th century. The figurative paintings of the Roman era, and especially the Carolingian period, are particularly important for understanding the evolution of certain iconographic Christian themes, such as the Last Judgement. - in: http://whc.unesco.org/en/list/269
