This guide documents significant 20th-century architecture in Piedmont in a chronological range (from the 1902 Exposition of Decorative Arts to the 2006 Winter Olympic Games in Turin) and provides the reader with a precise viewpoint for analysis: great events are seen as a stimulus and opportunity for confirmation for Turin and Piedmont and a moment for comparison with other architects and traditions. The Guide provides an unusual and alternative description of the city, signalling public and private 'temporary living spaces', selected and interpreted according to criteria that at times favour a named interior design, at others a 'spontaneous' but stimulating furnishing arrangement, at others again episodes of artistic contamination. Not all the best-known places, therefore, but those that are less known, to bring to the eyes of tourists - but also to those of the city's inhabitants - who want to discover the more unusual aspects of a post-industrial metropolis.
