The Romans were the first to recognize the tourism potential of the natural hot springs, which bubble at a rate of 250,000 gallons a day. These steamy facilities were discovered in the late 1800s, and the restoration and accompanying museum are excellent. The Victorians mounted a proud colonnade around the excavation, and water has long been drawn in the adjoining Pump Room; you can drink a glass of the sulfuric stuff if you like, or settle down for a pricey lunch in neoclassical style. It’s been the done thing in Bath since your great-great-great-grandma was in bloomers.
