Abstract Urban spaces are full of memories that are permanent in the minds of inhabitants and also visitors. Sometimes memories are individual and have a significant place in the biography of a person and sometimes are collective and common among all citizens and members of a society. Events in a city create memories and memories create lives. Memory-maker spaces of the past are forgotten or degraded. Therefore reduction of proper backgrounds for occurrence of urban events and social interactions has led to the reduction of dependency emotions of citizens to a space and cities are just a setting for frequent commutes. What inclines an urban space to memorability is subjective and objective evidences of semiotic templates. Today the signs are faded in urban spaces and this is a preface for amnesia of urban spaces and subsequently effects on the meaningfulness of urban spaces. Therefore the signs are important tools for continuity and transfer of collective memories. In this regard this research aims to investigate the concept of collective memory and its retrieval and comparison in urban spaces with semiotic approach. Content analysis and deductive reasoning are the main methods to create the mental grounds of the research. Confirmatory factor analysis in LISREL software is used for statistical analysis. Results of the research show that although at the moment the perceptual and social and semantic codes (perpetual-mental components and social-temporal ones) of the sense of collective memory in urban spaces of Hasan-Abad square and Azadi Square have the most effect in memorability, perpetual codes and social codes have the highest effect in Azadi Square and Hasan-Abad square respectively which is justifiable with regard to the spatial characteristics of these two spaces (logical codes).

Urban areas are significant elements in the structure of cities which can increase social interactions, identity and meaningfulness, formation of mental pictures and formation of the sense of collective memory. Urban areas show integrated structure of spatial organization of a city in which not only the connection of form and practice are to be considered, but also the meaning will find its place in whole complicated system of a city. Since forming the sense of collective memory has always been among the most basic qualitative principles and concepts in urban areas, finding a new approach to which can carefully explore the formative layers of urban areas is a priority. These layers are helpful in finding useful solutions for memorability of spaces and qualitative promotion of them.
Rollan Burt believes before any comment about the city, the technique of symbols should be utilized. With this new approach it seems it is possible to explore urban spaces and also to reach new solutions in the direction of the meaningfulness of a space and increasing the sense of collective memory. In this regard the objective of this research is to explore the concept of collective memory and its retrieval in urban areas with semiotic approach. Therefore the present research wants to discover the effective components on formation of the sense of collective memory on one hand and represent the conceptual template of semiotic on the other hand which is concealed in urban areas regarding the retrieval of memorability of urban spaces.Research is exploratory-explanatory and in the process of its decision making, an analytic comparison is used. Analysis of content and deductive reasoning is the main method to create the mental grounds of the research. Results express that the amount of memorability of Hasan-Abad square as an urban space based on the conceptual template presented in recent years and because of recent decisions of urban management has faded out. To retrieve the memorability, operational indexes of suggested semiotic templates in the frame of perceptual and social codes can revive the memorability of this square.
