Blanchland got its name from the white habits worn by monks of the Premonstratensian order who founded Blanchland Abbey. Built in the 13th century, the abbey survived until the 16th century when it fell into ruin. Parts of the Abbey survive including St Mary's, which was rebuilt in 1751-52. The interior has magnificent arches restored, rebuilt from the great work of the medieval stone masons. Other features of interest include several medieval grave slabs. This is a Grade I listed building. The abbey gatehouse survives and the unique thing about Blanchland is that the village stands on the footprint of the abbey, so it is possible to see the layout of the abbey, including the guesthouse, kitchen and prior's lodging that now form The Lord Crewe Arms.
