"The Lancashire Asylums Board was established in 1891, by the county council and all fifteen of the county boroughs. Ten years later the Lancashire Inebriates Acts Board was established, but the County Borough of Oldham did not participate. The Inebriates Acts Board built a reformatory at Brockhall (in the Ribble Valley, but its function gradually changed and by 1920 it was a certified institution for mental defectives. 1925 saw the dissolution of the Inebriates Acts Board and the Asylums Board became the Lancashire Mental Hospitals Board."
