This extravagant ancient bath complex is an excellent example of Ancient Roman spa architecture dating back as far as 43CE. Built around three hot springs that steam and bubble at a constant 46 degrees centigrade (115 degrees fahrenheit), the baths offer insight into the daily life of the Romans. A Sacred Spring feeds the Great Bath and the complex opens out into a series of changing rooms and baths to either side of the central bath. As per tradition, there is also a cold plunge pool for bathers to cool off after a hot sauna. The complex also features a temple devoted to Sulis Minerva, the Celtic goddess of healing and fertility that the Romans worshipped as Minerva Medica. Exhibits and Roman artifacts include a famous stone relief of the Gorgon's Head, mosaics, stone coffins, and a gilded head from a statue of Sulis Minerva.
