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 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."
The Forth Bridge, designed by Sir Benjamin Baker and Sir John Fowler, which opened in 1890, and is now owned by Network Rail, is designated as a Category A listed building by Historic Environment Scotland.
