Livio Vacchini (1933–2007) stands among the most revered architects of his era. His work was defined by an unrelenting pursuit of perfection and a continual interrogation of architecture’s fundamental principles. This collection of twelve essays—each focused on an architectural masterpiece, from Stonehenge, the Pyramids of Giza, and the Parthenon to Le Corbusier’s Notre-Dame-du-Haut and Mies van der Rohe’s Neue Nationalgalerie—continues the effort to share Vacchini’s vision and thinking with a broader audience. To that end this little book presents a new English edition of Capolavori—a small yet profound work, rich in meaning and poetry, written by the Ticinese architect in 2006, shortly before his death.
