This is Caerleon, a Welsh town just over the river from Bristol.
Back in the Roman days, there were three larger/permanent fortresses, at Deva (Chester), Eboracum (York) and Isca (Caerleon). This is the fortress’s barracks.
The nearby amphitheature was unfortunately, due to the weather.
Back in town is the National Roman Legion Museum, a small museum with lots of artefacts related to Roman life with an emphasis on military.
Headstones and a coffin. The coffin has a bones and skull in it (as found).
Out the back they’ve recreated a Roman garden.
And then down the road is the fortress’s bath.
Roman baths have a series of bathing rooms in dfferent temperatures. Sometimes they also have a swimming pool, as here and at Bath.
They say this pool is bigger than the one at Bath.
This is the frigidarium, the cold room.
