Helmington Row hospital was built in c1904 as a hospital for infectious diseases. HolyWell spring is close to the hospital. There are stories about the medicinal properties of the spring. A reference in 1805, a hundred years before the hospital was built, identifies the medicinal properties of a spring near Hunwick, which could be HolyWell Spring or maybe the Furnival Spring?
“There is a cold spring near Hunwick, Durham where parents and nurses bathed their children, with good effect, for rickets.” (The Traveller’s Guide; Or, English Itinerary—By Walley Chamberlain Oulton · 1805)
