If you’ve read Jane Austin, you’re familiar with how trendy it was during the Georgian period for parties of people and particularly sickly women to take the ancient waters at Bath; something that generally turned into a social/tourist outing in which young people would happily subject themselves to a variety of entertainment. Not entirely unlike Bath currently; tourists still flock, and many treat themselves to a spa day or two. Not in the Roman Baths themselves, mind you, although you can have a drink of warm water flavored with minerals from the fountain there.
These Roman baths are supposed to be some of the best-preserved anywhere, which according to the probably inexpert opinion of a local tour guide is due largely to the fact that they were buried under layers of mud for many centuries and thus were kept from marauding Anglo-Saxons, Norman conquerors and peasant farmers looking for stone to quarry. The Romans built on the site sacred to Sulis, a Celtic goddess that they combined syncretistically with Minerva. Before the Romans, the waters at Bath were said to have miraculously cured a Celtic king and his pigs of leprosy.
The modern city of Bath is a world heritage site and as such has to follow strict building codes to enforce the uniform look of the city. Local limestone is used exclusively for the facades of buildings.
