Atlas Mills in Bolton were, their heyday, one of the largest concentrations of cotton spinning capacity on one site in the country, with over 400,000 spindles in use and some 2,000 people employed across 8 mills owned by the Musgrave Spinning Company.
Musgrave had collapsed by 1926, and the area went into decline over many years. Although mills 6,7 and 8 remain, the rest are long demolished. Hampson painted the decline of Atlas Mills many times, using a variety of names including Victory Mill (after the area of Bolton) and Musgrave Mill.
The Bolton Steam Museum's website (http://www.nmes.org/museum.html) has some interesting old photographs of the site.
