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. The medieval monastery Abbot Odilo of Cluny, who resided more than once in Romainmôtier, had the present church built at the end of the 10th century. This church was modeled after the second church of Cluny Abbey (Cluny II). At the beginning of the 12th century, the church was modified by the construction of an ornate narthex and in the 13th century of a gatehouse. The last modifications were made to the church in 1445. The monastery church of Romainmôtier is one of the most important examples of Cluniac Romanesque art in Switzerland. While Odilo had managed Romainmôtier himself, his successors remained at Cluny Abbey and were represented by a prior. Until the end of the 12th century, this office was only granted for a limited number of years; later it became a lifetime appointment. In the 10th and 11th centuries, the monastery was fighting against aristocratic families of the region (Grandson, Salins) who were trying to expand their estates at the expense of the priory. These conflicts ended at the beginning of the 12th century. However, the pariage of 1181, in which Beatrix of Burgundy, the wife of Frederick Barbarossa, and the priory divided their rights, appears not to have been followed. Until the 14th century the priory was under Imperial protection. The lord of Les Clées exercised oversight on behalf of his feudal lords, particularly the Savoys. The property of the priory included the territory around the monastery, which was known as La Poté (derived from the Latin word potestas), or Terre de Romainmôtier. By 1050, this property consisted of twelve villages. The priory also possessed land in Apples and in Bannans in Franche-Comté. They owned rights or smallholdings in 45 other locations. In the 12th century, small priories were established in Bursins, Mollens, Vufflens-la-Ville, Vallorbe and Lay-Damvautier
