The Pré-Saint-Didier thermal springs were already known to the Romans, but it was only during the mid 1600s that they started to become a profitable activity, thanks to the first visitors who came to this beautiful valley to “take the waters”. This is how tourism originated in Valle d’Aosta.

The Spa reached its period of greatest splendour between the beginning of the 19th century and the first half of the 20th century. The building of the Spa dates back to 1834, while in 1888 the Casino opened its doors right next door.

For over 150 years the Spa was one of the major attractions of the Valley, hosting illustrious names and turning into the Italian Royal Family’s favourite holiday resort.
