Memorials
Richard Arkwright's barber shop in Churchgate, Bolton was demolished early in the 20th century. There is a small plaque above the door of the building that replaced it, recording Arkwright's occupancy.
A Greater London Council blue plaque unveiled in 1984 commemorates Arkwright at 8 Adam Street in Charing Cross, London.
Arkwright lived at Rock House in Cromford, opposite his original mill. In 1788 he purchased an estate from William Nightingale (the father of Florence Nightingale), for £20,000 and set about building Willersley Castle for himself and his family. However just as the building was completed it was destroyed by fire, and Arkwright was forced to wait a further two years whilst it was rebuilt. He died aged 59 in 1792, never having lived in the castle, which was completed only after his death. After being a hotel owned by the Christian Guild company, Willersley Castle now belongs to outdoor adventure education company Manor Adventure.
The Arkwright Society, set up after the bicentenary of Cromford Mill, owns the mill complex and has worked to restore it. Derwent Valley Mills, including this site, was declared by Historic England as "one of the country's 100 irreplaceable sites". It is also the centrepiece of the Derwent Valley Mills UNESCO World Heritage Site.
The Arkwright Scholarships Trust was set up in the UK in 1991 in Arkwright's memory to give scholarships to aspiring future leaders in engineering and technical design. By 2014, the Trust was awarding approximately 400 scholarships annually to support students through their 'A' levels and Scottish Highers, and to assist young people undertaking higher-level apprenticeships and university engineering studies. It had awarded over 5,000 scholarships as of mid 2020.
