Thermae Spa video:
"The Bath Hot Springs rise in the centre of the city of Bath in Somerset. Around 1.3 million litres of water flow from the springs every day at a temperature of around 40 °C. There is some debate about the source of the water but the generally accepted hypothesis is that rain water falling on the Mendip Hills to the south of the city infiltrates the Carboniferous Limestone and flows to the north, beneath the North Somerset coal field reaching a depth of 2.5 km from where it obtains its heat. It then rises up through fractures in the Jurassic rocks beneath the city. The chemistry of the water is dominated by calcium and sulphate with sodium and chloride also in high concentration
Returning to the Therme Spa, I had a wonderful morning in the pools, and I have to admit, I felt great. The placebo effect? Perhaps, but I'll take it. Highly recommended if you are in Bath. I was definitely invigorated! Below, since pictures are not allowed inside, for obvious reasons, this is from the website. It perfectly captures the ambiance of the open-air pool.

All of this was based on the treatment of almost any complaints people could imagine and the existence of all kinds of care, from quacks and snake oil salesmen to doctors who actually studied medicine. Below, Hospital of St. John the Baptist, Founded 1174, an alms house still in operation.
