Now that Le Corbusier's architectural oeuvre has been nominated for the third time for inclusion in the list of UNESCO World Heritage Sites, it is useful to revisit one of his icons built in the aftermath of World War II: the Unité d’Habitation in Marseille. Far from wishing to retrace the genesis of this outstanding building, it is a different story that I would like to sketch out here. Less well known, it is, however, fundamental to the material understanding and conservation of modern architecture. It is a history of the many repairs and other restoration projects that have accompanied this monument of 20th century architecture ever since its inception.
