The Workhouse, also known as Greet House, in the town of Southwell, Nottinghamshire, England, is a museum operated by the National Trust. Built in 1824, it was the prototype of the 19th-century workhouse, and was cited by the Royal Commission on the poor law as the best example among the existing workhouses, before the resulting New Poor Law of 1834 led to the construction of workhouses across the country.
