Cluny Abbey
In the 9th century Romainmôtier saw another period of decline. Lay abbots took possession of the monastery. In 888, the Guelph King Rudolf I of Burgundy gave the priory and its lands to his sister Adelheid or Adelaide, the wife of the Duke of Burgundy, Richard II. On 14 June 928/929, Adelaide gave the monastery and its lands to Cluny Abbey. However, for the monastery nothing changed because it remained a possession of the Burgundian royal family. During this period, the monastery was home to a community of Canons Regular rather than monks. At some point between 966 and 990, King Conrad of Burgundy finally renounced all his rights and gave the monastery to Abbot Maiolus of Cluny. Under Cluny Abbey, Romainmôtier Priory experienced its third golden age.
