A series of name-changes and re-organisations followed - in 1940 it became the Ministry of Works, then the Ministry of Works and Planning (1942-1943), followed by the Ministry of Housing and Local Government and then the Ministry of Public Building and Works from 1962. It subsequently was subsumed into the Department of the Environment in 1970 and then, in 1984, English Heritage.
