This singular work is one of the most outstanding buildings of the last decade in the oeuvre of Alvaro Siza, Pritzker Prize recipient in 1992. On a high plain by the river in the Roman city of Chaves, deep in the interior of his home country, Siza has built the Nadir Afonso Museum. Blending the modernity of elevation of the ground (and above the river's flood plain) and a vernacular indented plan, the building reveals the exceptional mastery of this architect and the very condition of contemporary architecture. The collection Architectural File presents a close look at particular works of some of the world's greatest architects. Each volume contains an extended photographic essay, a critical interpretation by a respected specialist and an exploratory text by a renowned author from outside the field of architecture, proposing a different view of the project. A selected bibliography, chronology and a fold out poster assembling technical drawings and working details, provide the reader with a decisive insight into the work. 37 photo plates, 38 technical drawings and images
