Abstract
The research explores the topic of heritage between tradition and modernity, in particular water management technologies through a series of examples in different contexts of Sardinia. Through the study of that relation, the thesis provides an important item for the project of architecture in weak context where water and land are strictly related. The research has the aim to explore the multi-scalarity through that show the relationship between water and architecture, from the territorial system to the building object. The recovery of the objects in the territories could be an important way to recovery not only a building but also a territorial system.
