Hydrotherapy was one of the mainstays of the town of Ponte Caldelas from the late 19th to the early 20th century. The properties of the waters have been well-known since ancient times, but the discovery of an excellent spring of medicinal waters in 1877 would give rise to the construction of the spa. Ponte Caldelas became popular for the quality of these medicinal waters, but a fire in 1914 would result in the end of the golden age of the town.
The bridge is also worth mentioning. It was built at the turn of the 16th century and, in 1809, it witnessed a battle against the army commanded by the marshal general Soult. In the town, there are amazing settings, squares and gardens, apart from some iconic buildings and houses built by Spanish migrants in America.
