This is the Bath Abbey, a church with some very interesting sculptures on the outside. If you look closely, you can see ladders with people climbing up them carved into the front facade.
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.
