The paper presents some results of a research on the digital reconstruction of some bridges designed by Andrea Palladio. The use of new technologies has enabled us to investigate the morphology of every single element and to be compared each other. Using the method of video animation, we have analyzed some of them in order to simulate the human perception and to understand their spatial configuration, but also to visualize the point of view of a man crossing a river or a canal. The last step was to prepare the models for producing some physical maquettes with the technique of rapid prototyping that have enabled us to verify the quality of the digital construction. Some different kinds of powder were used to identify the best one for the representation of architecture.
