The Roman Baths of Bath were built in the time of Emperor Vespasian, in AD 75, in the city then called Aquae Sulis. In fact, it seems that in this area, since 10000 BC, water leaked from the subsoil, still visible today.
They were known throughout the Roman Empire and frequented by people of all social classes. The complex also included a temple dedicated to Sulis, an ancient Celtic goddess of water, and to the Roman goddess Minerva.
