THIS photo was captioned 'visiting day at Children's Fever Hospital' 1904.

This was in the days before the discovery of antibiotics, when dreaded diseases like scarlet fever, diphtheria and tuberculosis were potential killers.

The closest that anxious parents got to their children being treated in the Blackburn Corporation Hospital for Infectious Diseases on visiting days was a glimpse of them through the windows.

This system prevailed until the 1950s.

It was built 600feet above sea level and 200feet above the town, in accordance with the belief that the supposedly-better air found at altitude was beneficial to tuberculosis cases.

The hospital - present day Park Lee - also set up a residential open air school in the grounds in 1923.

Costing £20,000, the hospital reopened in 1894.
