For almost a century the world renowned chest hospital, the Royal National Hospital specialised in treating the killer disease, tuberculosis. When the half-mile long building was demolished in 1969, the site became a botanic garden. The hospital was haunted long before this, and even today long-dead patients are still seen and heard. Ghostly weeping, groaning, smells of ether and even hot Christmas punch are reported. A sickly, consumptive-looking ghost, and phantom nurses in old fashioned uniforms walk the gardens, a ghostly tennis match has been seen, and on occasion, the old hospital building has materialised briefly.
