As true promoters of thermal cities, organisers of treatment protocols and directors of thermal establishments, doctors were the initiators of water cities (along with their financial backers). The villa belonging to Dr. Roland - a doctor in Divonne up until 1925 - is located in the middle of a park designed to “enchant those undergoing treatment” and is now home to the thermal club.
