Balneario Carlos III is a distinguished historic thermal spa named in honour of King Charles III of Spain, the enlightened 18th-century monarch who championed the development of Spain's thermal resources as part of his broader programme of modernisation. The establishment draws on naturally bicarbonated mineral spring water to provide wellness treatments in a setting that evokes the classical grandeur of the Bourbon spa era. Among the most historically significant of Spain's balnearios, Carlos III combines a distinguished royal heritage with the exceptional character of its mineral spring water.
