Here is the Abbey from the side. We did not go inside as they charged (like everything in England) and we had already been in plenty of churches.
The baths were really cool. Basically the Romans created a large complex for bathing and swimming around 49 AD. They chose this spot because there is a geothermal vent that has a flow of 1.3 million litres per day of 46.5 degree celsius water.
The baths were originally uncovered in the 1800s and only about 5 feet of walls remained. Due to the city ground level rising 17 feet since the baths were built, they were underground. Columns and a second level were added after the ruins were found. *** The Romans were pretty clever in building channels to route the water from the thermal vent into the main pool. They even circulated it under the floor to heat it. Excess water overflowed into a drain. I did not take pictures but you can visit other portions of the bath including the spring where the water comes up with gas bubbles (sometimes big ones) rising to the surface. The bottom is lined with lead sheets to keep ground water from contaminating that bath. A hand shaped lead pipe leads hot water from the spring to another chamber. *** Of course the Romans thought it the work of a god that this water should be so hot and thus made this a very special bath. One thing on display were tiny squares of lead about 3x3 inches that had been found (in the spring I think) rolled or folded . These were curses written by people and thrown into the spring in hopes the gods would grant them. Many had been translated and were interesting to read. Some 18,000 of these have been found.
