In Europe, the development of water cities obeyed a common urban program, unfolding according to a spa plan that rationalized space while meeting the expectations of ever-increasing numbers of curists. From the spring, the therapeutic landscape spreads in concentric circles through the city, creating a soothing environment. The barycenter is the spring, which becomes a refreshment bar and is itself integrated into the “trinkhalle”, the starting point of the walk, the routine of the curist, which aims to stimulate the assimilation of the waters between two refreshment bars. Then comes the Kurhaus, the home of the visitor, where one can relax and socialize between two concerts in the kiosk. A few steps away, there is the ever larger and more luxurious spa. Then come the recreational and cultural spaces: concert halls, opera houses, theaters and casinos. A few more steps and it is the domain of hotels and innumerable villas inviting to the holiday. Finally, the day ends as it began, with a religious ceremony as cosmopolitan as the resort’s frequentation, in the synagogue, the temple, the Anglican or Orthodox church.
