Northern General Hospital. This occupies a large site and was originally built as the Sheffield Union Workhouse and Infirmary between 1876 and 1880 (Harman & Minnis 2004, 183-184). The infirmary and the workhouse became separate institutions in 1906. This polygon shows the area originally occupied by the Sheffield Union Workhouse called 'Fir Vale Workhouse'. The name was changed to the Northern General Hospital in 1967. Prior to the workhouse, the regular boundaries of the fields suggest parliamentary enclosure. The Brightside award is dated 1795 (English 1985, 25). Adjacent to the fields on the 1st edition OS map of 1854 is an area labelled 'Brush House Common' suggesting enclosure from common land. Legibility is significant as many of the workhouse buildings survive and are incorporated into the present hospital.
