Termas de São Vicente sits beside the Douro river valley near Penafiel, in a parish named after the spa itself. The waters, first identified by the Romans in 315 AD, are sodic sulphurous, hypomineralized, alkaline-bicarbonated and fluoridated, emerging at around 18.5°C. The site preserves what are described as the best-preserved Roman baths in the country, alongside a modern balneotherapy complex and Palace Hotel & Spa. Treatments focus on respiratory tract and musculoskeletal conditions.
The site contains what is described as the best-preserved Roman bath complex in Portugal, with the waters documented as identified by the Romans in 315 AD. The surrounding civil parish was renamed Termas de São Vicente in 2013 after the merger of three former parishes.
