The “Caldarium” was a hot bathing room with hot-water pool in ancient Rome. With mild inhalation steam enriched with ethereal essences and a room temperature of 45°C, the “Caldarium” is particularly suited to sauna fans who don't like it too hot. A visit of up to 20 minutes helps strengthen your immune system and prevent colds. Loosened muscles and detoxification of the skin are further positive effects. If you want to experience antique Roman bathing culture, visit the “Tepidarium” and “Laconium”.
