摘要
The paper deals with the urban space of Piazza del Governo in Enna, a town located in the center of Sicily. This square was realized in 1935 by the architect Salvatore Caronia Roberti and is representative of the 1930s＇ fascist regime. The aim of this research is the knowledge of this urban space： the historical references, the compositive choices, the planimetric layout and its geometric rigor, and the monumentality and representativeness of the buildings overlooking the square. The research used the tools of Survey and Representation to better understand the dimensional ratios both at the urban and architectural scale. We have carried out an integrated survey （direct, photogrammetric, 3D laser scanning） in order to acquire a whole set of information essential to describe, document, and appreciate all the features of this urban space. Our investigation started by analyzing the historical documents preserved at the Historic Archive of the city of Enna （project drawings, letters, and historical images） to better understand why some decisions have been taken. The final result represents the historical memory up-to-date of the whole urban space, and it allows any academics to investigate more about the project： the initial decisions, the conservation state, and the possible and more coherent interventions of maintenance and preservation.
