The course examines the natural and anthropogenic environment of Santorini, focusing on the forms that have been generated both by the processes of the volcanic and seismic subsoil of the island complex, and as a condition of occupation of the land in the caldera and rivers using local materials. The topographies of Santorini and their habitability constitute the theme for the study of the Theranian cultural continuum, from the house of Akrotiri, the traditional and modern heritage to the contemporary condition, with the aim of a modern interpretation of the local architectural idiom in the 20th and 21st centuries.
