Initially a
Savigniac foundation out of
Normandy, the abbey was taken over by the Cistercian order from
Burgundy and responsibility for it was taken by
Byland Abbey. Founded in 1145 at Fors near
Aysgarth, it was moved ten years later to a site a few miles away on the banks of the
River Ure. In 1145, in the reign of
King Stephen,
Akarius Fitz Bardolph, Lord of
Ravensworth, gave Peter de Quinciano, a
monk from Savigny, land at Fors and Worton, in Wensleydale, to build a monastery of their order. The monastery was successively called the Abbey of Fors, Jervaulx and Charity. Grange, west-north-west of Aysgarth, a hamlet in the township of
Low Abbotside in the parish of Aysgarth, is the original site of Fors Abbey. After it was abandoned it was known as Dale Grange and now by that of the Grange alone. Serlo, Abbot of Savigny, disapproved of the foundation, since it had been made without his knowledge and consent. He refused to supply it with monks from his abbey because of the great difficulties experienced by those he had previously sent to England. Therefore in a general chapter he proposed that it be transferred to the Abbey of Belland (Byland), which was closer and would be able to provide the assistance required by the new foundation. Monks were sent from Byland and after they had undergone great hardships because of the meagreness of their endowment and sterility of their lands
Conan, son of
Alan, 1st Earl of Richmond, greatly increased their revenues and in 1156 moved their monastery to its better location in East Witton. Here the monks erected a church and monastery, which, like most of the Cistercian order, was dedicated to St Mary. At the height of its prosperity the abbey owned half of the valley and was renowned for breeding horses, a tradition that remains in
Middleham to the present day. It was also the original home of
Wensleydale cheese, originally made with ewes' milk. In 1279 Abbot Philip of Jervaulx was murdered by one of his monks. His successor, Abbot Thomas, was initially accused of the crime, but a jury determined that he was not to blame, and another monk fled under outlawry. According to
John Speed, at the Dissolution the abbey was valued at . The last abbot,
Adam Sedbergh, joined the
Pilgrimage of Grace and was hanged at
Tyburn in June 1537, when the monastic property was forfeited to the king. ==Post Reformation==
