This lecture explores the typology of the dormitory in architecture, focusing on the bed landscape as a sleeping arrangement, the space and dream spheres of sleeping in art, literature, and architecture, and the bed as a founding element in the design of mountain huts. It also delves into the significance of the bed during the Covid-19 era and discusses the political aspects of accommodation. The session concludes with a jazz concert by Marcel Maffli, Fedia Amice, and Denis Maffli.
