Almirante Baths

Further info: This medieval hammam in the heart of Valencia features a lobby and three vaulted rooms with star-shaped skylights. Bathers began in the cold room, the only part of the building to preserve part of the medieval pavement, then moved to the warm room to lather up, and finally enjoyed the hot room, where steam was generated by an adjoining oven that boiled the water. The high-temperature air produced by the boiler fire expanded through a low-ceiling chamber, called a hypocaust, located under the hot room.

Price: Free entrance.
