Wardon or Warden Abbey, Bedfordshire, was one of the senior Cistercian houses of England, founded about 1135 from Rievaulx Abbey. It is a Grade I listed building.

Rievaulx Abbey was a Cistercian abbey in Rievaulx, near Helmsley, in the North York Moors National Park, North Yorkshire, England. It was one of the great abbeys in England until it was seized in 1538 under Henry VIII during the Dissolution of the Monasteries. The wider site was awarded Scheduled Ancient Monument status in 1915 and the abbey was brought into the care of the then Ministry of Works in 1917. The ruins of its main buildings are today a tourist attraction, owned and maintained by English Heritage.
