During the 1930s Lancashire Constabulary was the second largest force in the country after the Metropolitan Police.
With a patch encompassing modern day Greater Manchester and Merseyside as well as the current boundaries, Lancashire was the largest county force in the country with a manpower to match. To ensure officers were up to standard the force established a new training school at Stanley Grange, Hoghton, near Preston, in the 1930s.
