The National Heritage List for England
Descriptions of each record
Some entries include maps to aid understanding of location but care is needed in interpreting their meaning and accuracy. There are explanatory notes with each plan.
Use of map data in the official record
Most listed buildings are marked on the map by a triangular point. The original designation used an address only to identify the location of the building, and the map marker has been added later. It does not form a part of the official record.
For list entries post-dating 4 April 2011 the map does form part of the official record but it only aids identification of the principal listed building. Protection may extend to attached objects and structures 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 (1).
