Bath: the Roman Baths

In the Great Bath, more than 1 million litres of water a day
rises from the natural hot spring at a temperature of 46 C!

My favourite part of Bath was the Roman Baths. The hot springs at this site were considered sacred before the Romans came, and the Romans built a temple on the site around 60-70 CE; the building complex grew over the next 300 years to include various bathing facilities and other structures.

Here's a model of the complex during its heyday:

Most of this is gone now, but the Great Bath and a few others remain. The Great Bath was definitely the highlight for me!

there were statues of Roman emperors
and generals spaced around the balcony of
the Great Bath; in the background is Bath Abbey

used to be, whereas now it's open to the air, since the
roof has long since been lost.

Aside from the Roman remains, there was also a great museum attached to the Baths, that explained their history and what life was like for the Romans, and displayed artifacts from archaeological excavations of the site. This isn't a very good picture (below) but it shows this computerized representation of the baths, with people walking around. A screen above it would zoom in to a particular person and give us details of what their life would have been like.
