We were told it should be something special, unique. It should fit in with Vals and attract new guests. In 1991 the project was presented at a village meeting with a water-filled stone model. Construction started in 1994, and the thermal baths were opened in 1996. Since then, over 40,000 people have visited them every year. Since completion, the overnight stays in the village and in the Hotel Therme have increased by about 45 per cent.
