The medicinal spring that once drew kings and famous diarists to Surrey
In short: Before it was a racing hub, Epsom was a premier spa destination. Driven by mineral-rich waters found where chalk meets clay, the town attracted royalty like Charles II and celebrated writers, until economic shifts and synthetic alternatives changed its destiny forever.
The town's unique geography, situated on the spring line where permeable North Downs chalk meets impermeable London Clay, created a natural aquifer. This allowed tributaries of the Hogsmill River to rise, producing waters rich in magnesium sulphate—famously known as Epsom salts. While tradition credits farmer Henry Wicker with discovering the spring in 1618 after noticing his cows avoided it, physicians had already noted its 'bitter purging salt' properties by 1603.
During the 17th and early 18th centuries, Epsom became a fashionable retreat. The spa attracted high-profile figures, including Charles II, who met his mistress Nell Gwyn there, and prominent diarists such as Samuel Pepys and John Aubrey. However, the experience was not without its flaws; the writer Dorothy Osborne complained in 1653 that the water required overnight settling to remove sediment, while Celia Fiennes noted that the spring often ran dry, forcing locals to dilute it with well water.
The town's prosperity as a resort declined sharply in the 1720s. This was driven by the economic fallout of the South Sea Bubble and intense competition from established spa towns like Bath and Tunbridge Wells. By the 1750s, the rise of commercially manufactured synthetic Epsom salts rendered the natural spring less essential. While the spa's influence faded, the town's identity shifted toward organized horse racing on the Downs, which had been established as a sport since the early 17th century.
