I would like to know what definitions you are applying for “conservation areas and historic battlefields”.
A conservation area is as defined under the provisions of the Planning (Listed Buildings and Conservation Areas) Act 1990 as amended by the Historic Environment (Wales) Act 2016 and subordinate legislation. There are over 500 such areas in Wales that have been designated by local planning authorities. The local planning authority determines “which parts of their area are areas of special architectural or historic interest the character or appearance of which is it desirable to preserve or enhance”. Such areas are then designated as conservation areas.
Cadw tasked the Royal Commission on the Ancient and Historical Monuments of Wales to create an inventory of historic battlefields in Wales. As part of this process the inventory adopted the following definition of a battlefield:
An area or location, terrestrial or marine, where a conflict occurred, involving military forces. All aspects of Wales’s past should be considered for the identification of historic battlefield sites, which may include traditional battles, sieges, invasions, skirmishes, ambushes, massacres and sites of civil unrest.
Over 700 battlefields have been identified, ranging from battles of the Roman period to outbreaks of civil unrest in the nineteenth century.
