Blanchland Abbey at Blanchland, in the English county of Northumberland, was founded as a premonstratensian priory in 1165 by Walter de Bolbec II, and was a daughter house of Croxton Abbey in Leicestershire. It became an abbey in the late 13th century. The 16th century former Abbot's house (now The Lord Crewe Arms Hotel) is a Grade II* listed building and the whole site is a Scheduled Ancient Monument.
The abbey granges were pillaged during the Anglo-Scots wars, in particular during 1327, but the abbey itself was apparently left unscathed. There is however a legend that during one raid in the area, the monks prayed that the abbey would be spared. Subsequently, a mist descended which shielded the valley and monastery from view and was overlooked by the Scottish raiders, who passed by. The foolish monks upon hearing this, proceeded to ring the abbey bells to signal to every one in the valley that it was safe, that the invaders had passed. During their celebration of bell ringing, the Scottish invaders heard the bells, turned around and ransacked the Monastery.
The abbey was dissolved in 1539 and granted to the Bellow and Broxholm families. It was later acquired by the Radclyffe family from whom it passed by marriage to Nicholas Forster. Part of the abbey church was altered and retained for use as the parish church, and the abbots' former residence became the manor house. In 1612, it was the residence of Sir Claudius Forster, High Sheriff of Northumberland.
