This is a faithful reproduction of the pages devoted to the project “Viterbo: Redevelopment of the Faul Valley 1980”, one of the six projects by Dario Passi presented in Dario Passi - Architettura di città. Sei progetti (Edizioni Kappa / AAM Roma, 1982), a book in the series “Progetto/Dettaglio” directed by Francesco Moschini and produced in relation to the homonymous exhibition, that took place in Rome at the gallery AAM Architettura Arte Moderna, in February 1982.

Our deepest gratitude goes to Francesco Moschini for all of his help in publishing this book.
