The municipality of Pré-Saint-Didier is located in the autonomous region of Aosta Valley, precisely in the Valdigne, the upper valley of the Dora Baltea. The hot springs of Pré-Saint-Didier were already known during the Roman Empire, when the village was called "Arebrigium", but they were not exploited until the second half of 1600.

Instead, the historic resort was constructed in 1834 and for more than 150 years the hot springs had been one of the main attractions of the Italian royal family. Due to the two great World Wars the thermal baths of Pré-Saint-Didier lost their popularity and in 1976 the resort was definitely closed. After about thirty years of inactivity, in 2005, the building was restored and reopened, increasing the number of tourists and enhancing in this way the local economy.
