Historic Scotland is the Scottish agency which safeguards the nation's historic environment and promotes its understanding and enjoyment on behalf of Scottish Ministers.
It is not to be confused with the National Trust for Scotland.
In Scotland, historic buildings are listed in three categories. According to Historic Scotland's criteria the categories are defined:
Category A: Buildings of national or international importance, either architectural or historic, or fine little-altered examples of some particular period, style or building type.
Category B: Buildings of regional or more than local importance, or major examples of some particular period, style or building type which may have been altered.
Category C(S): Buildings of local importance, lesser examples of any period, style or building type, as originally constructed or altered; and simple, traditional buildings which group well with others in categories A and B or are part of a planned group such as an estate or an industrial complex.
Buildings may also be linked in A or B class groups to indicate their position in relation to a wider set of buildings with which they form a related whole such as an industrial estate, an urban square or a village high street.
