The idea of conservation and its relationship with hypogean and underground spaces.

The MIAW-Milan International Architecture Workshop is the international intensive programme at the Politecnico di Milano, School of Architecture Urban Planning Construction Engineering, that provides an international design forum for schools, teachers and students, but it is also an informal platform to discuss issues and share ambitions that education implies. It aims to stimulate cross-over thinking between researchers and practitioners in the design field, involving different scales and encouraging an interdisciplinary approach towards design problems. Each class has an international guest professor with a high profile whose activity and interests are related to the different study courses and disciplinary areas characterising our school. The author's contribution to the topic "Archives of Memory" is related to the conservation hypothesis of objects, documents and works of art that led to underground, protected and often inaccessible spaces. The idea of conservation and protection, as opposed to dispersion and loss, implies the desire to maintain works of art, products and objects that must guarantee long-term durability.
