Now it's time to change elements, from earth to water. People have been visiting Caldes de Montbui at least since Roman times to take advantage of the curative powers of its waters. One of the water’s peculiarities is the temperature at which it emerges from the earth, as you'll find out if you dip your hand into it at the popular Font de Lleó: be careful because the water streams from the lion’s mouth at a temperature of 74 degrees Celsius (165 degrees Fahrenheit). The square that the lion gives its name to features many interesting sights: the elegant Broquetas hotel and spa; the modern town hall; what are reputed to be the best-conserved Roman baths on the Iberian Peninsula; and the Thermalia museum, where you can find out about the history of Caldes, see works of art by famous artists and get all of the information you need, since it also functions as a tourist information office.
For example, you can ask about other sights to see in the town, and they'll probably mention the medieval walls, the Romanesque bridge, the mill of L’Esclop, the old Codina pharmacy, the Delger museum, various washing places, and Can Sanmartí, where pasta has been made since 1700. Moreover, at the beginning of Carrer Bella you'll find a magnificent tower, which was originally part of the 12th-century wall and was later used as a prison, and which is now considered to be a cultural asset of national interest.
We also recommend that you cross the bridge and step into Can Rius park, the old garden of the spa of the same name, which is now closed to the public, though a part of the building has been beautifully restored and activities are held there. You can easily spend a whole day exploring Caldes, and even more if you've booked a thermal circuit or treatment at any of the town’s establishments.
