Certainly worth a morning looking around the interesting Roman Baths. Quite expensive however worth the money if you are interested in the history of Bath and the roman influence on the town.
Water rises from the "sacred spring" at a rate exceeding a million litres a day and at a temperature of 46C.
Just a warning -- there is a mostly good, but interminable museum between the upper and lower views of the baths. If you are short of time, don't get hung up there!
What we see today is the Great Bath -- lined in lead and 1.6 meters deep. It was originally covered by a vast barrel vaulted hall.
These well preserved Roman baths are one of the primary reasons for Bath's World Heritage designation. The main pools are restored and there is also a museum of the Roman artifacts.
The Baths are possible due to Hot Springs. The water from these hot springs were rumored to have magical healing powers.
When in Bath you must visit the Roman Baths! I believe you can get in free if you can proof you live in Bath!
I always wanted to write that one here as it list the activity as an example.
There really are Turkish baths too.
This is a picture of the healing well located in the mail lobby of the restraunt.
