Amongst its numerous mineral springs, the most important are those of Mehadia, with sulphurous waters, which were already known in the Roman period as the Thermae Herculis.
The site of the Samnite city, which in the 4th century B.C. had a coinage of its own, is not known; the Roman town lay in the valley of the Vulturnus, and its walls (4th century) enclose a circuit of 12 m., in which are preserved remains of large baths (Thermae Herculis) and a theatre.
