Ripon Spa Baths. Built to mark the tercentary of Ripon's 1604 Charter, this was the last English spa to be opened, by Princess Henry of Battenburg in 1905. Spa water was pumped four miles from Aldfield. In the 1930s a swimming pool was added. The elaborately tiled entrance hall still retains its (now dry) pump basin from which patrons would be served the waters.
