Dear Wikiwand AI, let's keep it short, summarize this topic like I'm... Ten years old or a College student
In the United Kingdom a listed building is a structure of particular architectural and/or historic interest deserving of special protection. Such buildings are placed on one of the four statutory lists maintained by Historic England in England, Historic Environment Scotland in Scotland, Cadw in Wales, and the Northern Ireland Environment Agency in Northern Ireland. The term has also been used in the Republic of Ireland, where buildings are protected under the Planning and Development Act 2000, although the statutory term in Ireland is "protected structure".
A listed building may not be demolished, extended, or altered without special permission from the local planning authority, which typically consults the relevant central government agency, particularly for significant alterations to the more notable listed buildings. In England and Wales, a national amenity society must be notified of any work to a listed building which involves any element of demolition.
Exemption from secular listed building control is provided for some buildings in current use for worship, but only in cases where the relevant religious organisation operates its own equivalent permissions procedure. Owners of listed buildings are, in some circumstances, compelled to repair and maintain them and can face criminal prosecution if they fail to do so or if they perform unauthorised alterations. When alterations are permitted, or when listed buildings are repaired or maintained, the owners are often required to use specific materials or techniques.
Although most sites appearing on the lists are buildings, other structures such as bridges, monuments, sculptures, war memorials, milestones and mileposts, and the Abbey Road zebra crossing made famous by the Beatles, are also listed. Ancient, military, and uninhabited structures, such as Stonehenge, are sometimes instead classified as scheduled monuments and are protected by separate legislation. Cultural landscapes such as parks and gardens are currently "listed" on a non-statutory basis.
