The questionnaire is in the form of a Likert scale and the data analysis was done with the help of SPSS25 software and using the T.Student test. The sampling method was a simple random method.

Geographical area of research : Qazvin city has different types of urban and public spaces based on historical and geographical conditions. First, the types of urban and public spaces in this city have been classified into seven categories and then evaluated in a survey of citizens

Result and Discussion: The findings of the research showed that after the end of this epidemic, the behavioral patterns of citizens will have differences depending on their age group and gender. The elderly have the least desire to be in urban spaces in the post-corona period, on the other hand, the desire of citizens to visit urban spaces in the historical context of the city is not the same as in the past. Of course, women are more willing than men to use all kinds of urban spaces.

Conclusion: Despite the obligation of citizens to perform a large part of activities through virtual space during quarantine, but with the end of the restrictions, the surveys showed that virtual space can only be a suitable platform for carrying out essential activities and in the case of other selective activities or socially, the dominant desire of the society, even the young generation, is to be physically present in urban spaces.
