Poços de Caldas
Poços was founded in 1872. The region had been inhabited by the Cataguases Indians, who were expelled from their lands by the "Bandeiras Unidas Paulistas" during their quest for gold. The place was first called "Freguesia de Nossa Senhora da Saúde das Águas de Caldas" ("Parish of Our Lady of Health of Caldas Waters"). In 1874 it became a district, then in 1875 it was elevated to the category of city. It became famous after the discovery of the hot springs, and many important people began to visit the spa in search of cures provided by the water.
