The name Smithills derives from the
Old English smeþe meaning smooth and
hyll, a hill and was recorded as Smythell in 1322. Early
medieval records about the hall began in 1335 when William Radcliffe acquired the manor from the
Hultons who held it from the
Knights Hospitaller. On Radcliffe's death in 1369, it passed to his son and heir Sir Ralph Radcliffe,
High Sheriff of Lancashire for 1384–1387 and twice MP for
Lancashire. The Radciffes lived there until 1485, when the male line failed and Smithills Hall passed to the Bartons, wealthy sheep farmers who lived there for nearly 200 years. In 1659 the hall and estate passed by marriage to the Belasyse family. In 1722 the Byroms of Manchester bought the manor and kept it until 1801 when the hall and estate were acquired by the Ainsworths, who made their fortune as the owners of
bleachworks at
Barrow Bridge. In 1554
George Marsh, a preacher from
Deane near Bolton, was 'examined' at Smithills Hall, before being sent to
Chester to be tried for
heresy. He was found guilty and executed at
Boughton in Chester. A footprint, supposedly left by Marsh, is said to bleed every year on the anniversary of his death (24 April). File:Georgemarsh Footprint1.jpg|Sign claiming the footprint of George Marsh File:Georgemarsh Footprint2.jpg|The supposed footprint
Nathaniel Hawthorne visited and described the hall when he was United States
consul in
Liverpool in 1855. The demonstration is commemorated with a stone on Coalpit Road. It was a forerunner of the
Kinder Scout mass trespass. By 1996 the road was declared a public right of way. ==Architecture==
