The research aims to analyze how cinema could transcribe the experience lived in spaces and help to unveil architecture in layers other than just technical, formal and objective. For this, it uses the short film Sizígia (2012), in which architecture is not only an approached topic, but a fundamental part of its configuration. The short film by researcher Luis Urbano falls within the academic scope of architecture analysis and was filmed in the project Piscina das Marés (1959-65) by Portuguese architect Álvaro Siza. In Sizígia, the moving image was seen not only as a representation of architecture, but as a way of investigating space, exploring its qualities and its narrative potential. Cinema, as a form of expression, seeks to tell the plots of life lived in places through the moving image, connecting the dilemmas of human life to architecture. His language ends up capturing events, linking them to space and, as a consequence, his narrative reveals the architecture where the plot of life takes place. In this sense, research seeks in cinema an alternative means of investigation and representation of architecture.
