This study examines how the components of the urban environment and its functionalities influence the attractiveness of public squares (PSs), and how they affect daily activities. This research is based on direct observations and surveys questionnaires. Data were collected from two PSs: May1st1945 square (MS, N=173) and Mohamed Harsous square (HS, N=97), located in Batna city centre (Algeria). The inquiry first includes an evaluation of urban environment layouts; a second evaluation to determine variables linked to environmental functionalities and utilization, and a third evaluation to assess social activities through characteristics of practices. The findings reveal that the components of the urban environment and its functionalities directly influence the attractiveness of PSs, mainly through proximity and comfort, and that shopping and leisure activities are also important for their attractiveness, but remain insufficient. This shows that attractiveness depends on the duration and variety of activities, including the interaction of people with these components to foster sociability. In addition, the use of these squares as a function of age and gender, and their appropriations are dealt with, since they have a direct effect on their uses and people’s preferences.
