Oakwell Hospital
United Kingdom
Oakwell Hospital was originally a small fever hospital built on a hilltop in Birstall in West Riding of Yorkshire, England, caring for chiefly people with diphtheria and scarlet fever. From the mid-20th century it was repurposed as a geriatric care facility until in 1962, the elderly were transferred out as a smallpox outbreak in Bradford necessitated it to be designated for the isolation of cases of smallpox.
