took place in Aix in the Middle Ages and until the end of the 18th century, in the only existing Roman pool, outdoors, or at home where the spa water was brought by hand. The King of France Henry IV highly appreciated his Aix bath, according to Jean Baptiste Cabias. In 1737, to protect the hot springwater seepage from the stream running through the city, a major project was scheduled by the General Commissariat. This changed the urban distribution of the town centre, since it was necessary to dig a new bed for the Moulins stream, outside the walls. They also had to rebuild the four mills of the Marquis of Aix, until then in the town centre, along the new channel (currently Montée des moulins, Hill of Mills). It is the Duke of Chablais, son of King Victor Amadeus III, to whom Aix owes its renaissance because it was he who, after having tasted the benefit of sources and found it to be poorly housed, suggested the construction of a thermal establishment to the king. By royal appointment on 11 June 1776, King Victor Amadeus III commissioned Robiland to draw up plans for a bathing establishment. It was built from 1779 to 1783, under the direction of the engineer, Capellini. This date also marks the beginning of the demolition of the old town centre, as a result of this imposing construction, people began to clear the surrounding houses to create the place. This first thermal establishment became an important factor of development. Throughout this period and until the Revolution, the town hosted a roughly stable number of approximately 600 patients each year, the majority of them French. Consecutively, the population increased, reaching 1700 inhabitants in 1793. In 1783, to enhance the lives of the patients, the council of the municipality built a landscaped public promenade: le Gigot currently known as Square Alfred Boucher. It was then lined with chestnut trees and was drawn by architect Louis Lampro. Aside from private gardens, this is the first act of urban green space, which gave a boost to the development of the town at this side of the walls, along the road to Geneva. In 1792 the French revolutionary troops, under the command of Montesquiou, were in Savoy. The civilian use of the spa then stalled. The baths were requisitioned by the armies of the Republic, which sent the wounded soldiers for
