A listed building is a building, object or structure that has been judged to be of national historical or architectural interest, and so has been placed on the National Heritage List for England (NHLE).
Any object or structure fixed to a listed building, and any object or structure within the curtilage of the building (which although not fixed to the building, forms part of the land and has done so since before 1 July 1948) are also treated as part of the listed building.
