Snabdaugh is a rectangular late 15th or early 16th century defensible stone house, founded by the Heron family. Of two storeys and an attic, it forms the central section of a farmhouse, with the other attached ranges being 18th and early 19th century. An unusual feature is a pointed tunnel vault to the upper floor and the fine ashlar springing of a lower vault. The beams of the attic floor, rest on eight stone corbels inserted into the vault and on the west gable is a probable stair well. This type of domestic strong house is possibly derived from Scotland and if so, is unique in England. A mile west is Dally Castle and 3 miles east is Bellingham Castle.
