The assimilation of the architectural sign to the linguistic one, is the way that allow us to analyze the architectural element of the city, according to the symbolic and conventional way, but giving to the architectural sign an iconic value that we could read through reconstruction of city in films. It is possible if we consider city as artwork seen according to the definition of Lynch. There is a temporal and special dimension, the urban dimension, which would otherwise not be (...) ‘visible’ to the naked eye or perceivable with hearing. City as an artwork can be read for more reasons, through the cinema in the translation of an architectural semiotics that finds a double correspondence of Urbs and Civitas, in the real building of the city and in its re-construction. In this contest, some Italian movies of Rossellini, De Sica, Antonioni, for example, beyond the traditional interpretations, can give us indications about the moments and ‘points’ of collapse that we can find in ‘signs’ and ‘singular points’. It’s in these points that we found the signs of evolution, breakdown and collapse of relationship between Urbs and Civitas. (shrink)
