Sedgemoor is a local government district in the English county of Somerset. In the United Kingdom, the term listed building refers to a building or other structure officially designated as being of special architectural, historical or cultural significance; Grade II* structures are those considered to be "particularly significant buildings of more than local interest". Listing was begun by a provision in the Town and Country Planning Act 1947. Once listed, severe restrictions are imposed on the modifications allowed to a building's structure or its fittings. In England, the authority for listing under the Planning (Listed Buildings and Conservation Areas) Act 1990 rests with Historic England, a non-departmental public body sponsored by the Department for Digital, Culture, Media and Sport;
