The Abbey of Müstair, a Benedictine convent in Graubünden near the Italian border, holds the most complete cycle of Carolingian frescoes surviving anywhere in the world — painted around 800 AD, likely commissioned under Charlemagne himself. UNESCO listed the abbey in 1983. Swissmint's commemorative program has long favored Swiss heritage sites of this caliber, and the .835 fineness used here was the established Swiss commemorative silver standard of the period rather than a deliberate compositional choice.
