Fodor's Expert Review Royal Pump Room Museum

Built in 1842 over the sulfur well (as Europe's strongest, its pungent odor is still very much present) that made Harrogate a wellness destination, the Pump Room housed in this octagonal structure sold 1,500 glasses of water to spa-goers in its heyday (so no, designer water is not a modern phenomenon). Today it houses the town's museum, which has displays of bygone spa treatment paraphernalia alongside a somewhat eccentric collection of 19th-century clothes, fine china, and bicycles.
