Book excerpt: The theme of this book is between the response to environmental hazards - such as earthquakes of housing (of the so-called "other Modernism") - over issues of conservation of historical materials, as a kind of sustainable urban development which includes inhabitants' participation. It is important to preserve memory, and this book uses the knowledge of art, a multimedia installation, and the role of photography as an example of virtual witness. It includes a dialogue about traditional earthquake resistant natural materials with modern construction in order to learn lessons about retrofitting. (Series: Architecture / Architektur - Vol. 11)
