The baths were constructed in the 2nd century AD. The name of the facility derives from a no longer existing monastery on the site. The bath is accessible from Südallee.
At the time of the construction the Barbara Baths were presumably 565 x 788 ft (172 x 240 m) and thus the second largest bath of its type after the Baths of Trajan in Rome. Unfortunately, there is little visible of the once imposing size as the baths, like many other buildings, served as a stone quarry for centuries.
You can now experience the baths on a visitor's walkway built across the ruin. A total of nine information panels with reconstructions demonstrate to visitors the architecture and the splendid furnishings of the facility as well as the procedure of bathing in the Roman era. The development of the Barbara Baths after ancient times and the current measures for protecting the ruin are also shown.
