In the United Kingdom, a listed building is a structure of particular architectural or historical 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 Historic Environment Division of the Department for Communities in Northern Ireland. The classification schemes differ between England and Wales, Scotland, and 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".
