The first hydrographic study of the thermal springs of Vidago occurred in 1863,[1] following several years of visits by Portuguese locals and those seeking medical treatments.

[1] Between 2007 and 2008, owing to degradation, Grupo Unicer (the owners) began a program of remodelling and recuperation, in order to create a tourist holiday village, under the direction of architect Álvaro Siza Vieira.

The hotel is located in the millennium park of Vidago, encircled by various species of ancient trees (such as maples, pines and laurels), river runs, pedestrian trails and three natural mineral springs.

[1] In 2010, the hotel was completely refurbished by the contractor Casais, hired by Aquanattur, Unicer's touristic project for Vidago and Pedras Salgadas.

It included a sunk 3 metres (9.8 ft) pool, stained-glass windows and marble decorated with a mixture of Neoclassical and Moorish styles.
