The Müstair-based Convent of St. John dating from the year 775 AD with the largest cycle of early medieval frescoes in the world stemming from c. 800 AD is a jewel of fine art from the Carolingian period. The series of paintings which adorns the entire nave depicts, amongst other scenes, the beheading of John the Baptist. Müstair owes its existence and uniqueness to Charlemagne. The Carolingian church and its unique wall paintings raises this divine Alpine monastery to the standing of a world-heritage-listed site. Join in the discoveries! The nuns have only recently opened the late medieval Planta tower dating from 960 AD to the public. The new cloister museum contains many cultural treasures of times past.
