Terme di Stigliano, in Canale Monterano near Rome, sits within a 20-hectare hillside park containing five separate thermal springs, with water temperatures ranging from about 30°C to 38°C. Known to the Etruscans and later the Romans, who called it Thermae Stygianae, the site was studied by the Orsini family beginning in the 1400s, and the current hotel structure was built by the Altieri family in the 1700s. An imperial-era sweating grotto survives beneath the facility.
Known to the Etruscans and Romans, who renamed the site Thermae Stygianae after the mythical infernal river Styx; Pliny recorded that Roman troops returning from abroad had to purify themselves here before entering Rome. The site fell into disuse after the fall of the Roman Empire and regained importance in the 1400s under the Orsini family, with the current hotel building constructed by the Altieri family in the 1700s.
