All rights reserved.The urban square has been a prominent research topic in the literature of public space for decades, with related research taking it into account mainly as a physical, social, and economic space. However, a very limited number of empirical studies take into account the spatial perception of visitors to squares. The main aim of this study is to fill this gap by determining the factors prominent in shaping visitors’ perception of the attractiveness of urban squares. For this purpose, fourteen urban squares were selected as cases, and 644 randomly selected visitors of these squares were surveyed. Following this comprehensive survey, a binary probit model was used to model the visitors’ binary perceptions of the attractiveness of the related squares. A correlative approach between such a comprehensive study and an econometric model would be novel in the case of Istanbul.
