Queen Leonor (Rainha Dona Leonor, in Portuguese), the wife of King João II, is credited as the founder of Caldas da Rainha. One day in 1484, while traveling from Óbidos to Batalha, she happened upon a group of peasants bathing in foul-smelling waters by the roadside. The queen stopped to inquire about this oddity, and the bathers told her that the waters possessed curative powers. She decided to try them and was pleased to find that she was quickly relieved of an unknown affliction that she had been suffering. On that site, the queen ordered a hospital built so that others could enjoy the same relief. Construction began the following year, and although the first patients were admitted in 1488, the works were not completed until about 1496 or 1497. To finance the hospital and its adjoining church, the queen sold her jewels and used income from her landholdings. The name of the settlement that grew around the site and became Caldas da Rainha refers to both its founder and the reason for its existence. The city's name can be translated as "Queen's Hot Springs", "Queen's Spa", or "Queen's Baths". The settlement's waters remain its major claim to fame.
