In the 17th century, the capital of Savoy was a town of 5,000 inhabitants, surrounded by its medieval walls. It offers a multitude of architectural facets: mansions, convents, common houses and unsanitary hovels in the suburbs. The small and great Savoyard nobility, merchant bourgeoisie, small traders, soldiers in garrison, commoners and poor people come together there. Despite major works and the bombardment of 1944, the city center of Chambéry has managed to preserve a large part of the civil architecture of this period. This reference work is an invitation to travel back to the time of J.-J. Rousseau. Thanks to a fascinating text, unpublished extracts from the archives, two splendid series of watercolor plans, photos ..., the reader walks the city and discovers the daily life of the Chamberians with their joys, their sorrows and the significant events of their family and social life.
