Main Facts:
The Ancient Roman Baths of Diocletianopolis are among the best-preserved Roman thermal baths in Bulgaria and one of the highlights of Hisarya.

The mineral-rich waters, many of which still flow today, attracted visitors seeking treatment, relaxation, and recreation.

Meanwhile, information panels explain how the baths functioned and how the mineral water was distributed throughout the complex.
