Cheltenham
Cheltenham lies at the foot of the Cotswold hills in Gloucestershire. A market town for much of its history, it became known for mineral waters discovered around 1716. Henry Skillicorne developed the spring with a pump and assembly room, attracting visitors who came to drink the water. In 1788 George III and his family spent five weeks at Cheltenham, giving the spa a national reputation and encouraging the town's fashionable growth.
