These buildings are protected for their historic significance. There is a parallel system for ancient monuments, known as 'scheduling', which means that there is not a consistent approach to sites like castles, abbeys and henges, which may be listed, scheduled or both. In England, the listing is administered by Historic England, an agency of the government's Department for Digital, Culture, Media and Sport.
Buildings of outstanding architectural or historic interest are listed at Grade I, and of the approximately 372,905 listed buildings in England, over 9,000 (2.5%) are Grade I.[1] Estimates to the numbers of buildings do, however, vary given that separate listings apply to structurally separate buildings: therefore a street of houses can be listed as one building, but a church wall can be listed separately from the church. Some buildings are listed for their group value.
