According to the Derbyshire UK website;
Matlock Bath in Derbyshire, became an instant tourist resort for the wealthy and influential, when warm springs, at a constant temperature of 68 degrees Fahrenheit, were discovered back in 1698. The upheavals in Europe in the later part of the 18th century onwards discouraged the wealthy from making the Grand Tour and they diverted their attention to places like the Peak District. Matlock Bath was a beneficiary of this new era in travel.
No disrespect to the good people of Matlock, but I think it might be a bit of a disappointment compared to the treasures of Rome and Naples.
