Buildings and structures of national importance are given legal protection by being placed on a ‘List’ of Buildings of Special Architectural or Historic Interest. Under Section 1 of the Planning (Listed Buildings and Conservation Areas) Act 1990, the Welsh Ministers are required to compile and maintain this list.
The first Listing inspections were undertaken in the Post-War period. In the 1990s and early 2000s, the Historic Environment Service (Cadw) undertook a systematic programme of investigation across Wales called the ‘Re-survey of Wales’. During the re-survey the buildings in each Community area in Wales were assessed for Listing. Since the Re-survey, the Listing of buildings has continued on a thematic basis (to include some of the more modern building types) and on an adhoc basis. This process is ongoing.
In Wales there are over 29,000 buildings and structures on the list. Listed buildings range from Medieval Churches to modern commercial premises etc, structures can include railings, gate piers, walls, war memorials, gravestones, post boxes and telephone boxes etc.
Buildings on the List are given one of three grades which denote their level of importance, Grade I being the highest. The Grades are: -
- Grade I - Are of exceptional interest
- Grade II* - Are particularly important
- Grade II - Are of special interest
The Listing of buildings and structures is an ongoing process. Buildings and structures can also be removed from the List in a process called ‘De-Listing’. To avoid re-using old data, users should periodically obtain the latest version from Lle.
If the data is to be incorporated into a Geographic Information System, please note that point data only locates the listed building itself. It does not show the full extent of the listing which confers protection on any object or structure fixed to the listed building and which is ancillary to it, or is within the curtilage which forms part of the land and has done so since 1 July 1948. Some listings can comprise a single GIS point, however, it may refer to a number of buildings within the listing description, such as a terrace of houses. It is important not to rely only on this digital data as the primary source for identifying the listed building. The point depiction must be used in conjunction with the list description to ensure that the correct building has been identified. The list description is available online via Cof cymru - National Historic Assets of Wales.
Please note that when the dataset is downloaded from Lle in an ESRI shapefile format, the dataset is currently divided into two shapefiles, these are:-
Both of the datasets are to be used, as combined they form the Listed Building GIS dataset for Wales. This cause of this anomaly is under investigation.
