“The Broad Street cholera outbreak (or Golden Square outbreak) was a severe outbreak of cholera that occurred in 1854 near Broad Street … This outbreak, which killed 616 people, is best known for the physician John Snow’s study of its causes and his hypothesis that germ-contaminated water was the source of cholera … This discovery came to influence public health and the construction of improved sanitation facilities beginning in the mid-19th century …”, https://en.wikipedia.org/wiki/1854_Broad_Street_cholera_outbreak

A pump is now installed at the pub, off the original site.
