The remains of the roman Bath can be visited
Roman Bath Biriciana

In Weißenburg, Bavaria, the Roman Baths of Biriciana are located. They are among the well-preserved Roman bath complexes on Germanic soil and were once an integral part of the Roman fort and vicus Biriciana, which served to secure the Upper Germanic-Rhaetian Limes.
History+
The history of the baths spans three construction phases. The first complex was built around 90 AD as a simple row bath, concurrently with the fort. Around 130 AD, an expansion took place, adding, among other features, a caldarium, two tepidaria, a sudatorium, a frigidarium, and a basilica. After destruction, presumably during the Marcomannic Wars, a larger ring-type bath was erected around 180 AD. This third complex remained in use until it was damaged by Alamannic invasions around 230 AD and abandoned in 258/59 AD, after which individual rooms were repurposed for other uses.
