This book shows through historical data, diagrams and drawings, the design system of an Italian historic center, that of Vicenza, Italy. Vicenza is the result of an urban construction process that has as its model the invention of the Palladian design system. The main argument is how the architectural vision of Andrea Palladio shaped Vincenza to the city it is today. Vicenza is an example of a collective dream, an expression of the best Renaissance artistic culture, a classic example that a city can reform itself through intellectual activity.
