This study highlights the importance of social sustainability in the context of urban parks and evaluates its performance using a specific case study. It proposes a comprehensive measurement scale focused on eight dimensions: identity, sense of place, social cohesion, security and safety, equity, facilities, comfort, and accessibility, applied to Alaeddin Hill Park in Konya, Türkiye. Using a quantitative research approach and data collected from 120 participants, this study investigates these dimensions to understand their impact on the park’s social sustainability. The findings of this study reveal that, while Alaeddin Hill Park is highly valued for its identity, facilities, and social cohesion, it requires significant improvements in areas such as security and safety, sense of place, and comfort. Another finding indicates that lower-income respondents report higher levels of comfort and a stronger sense of identification with the park. This study offers practical recommendations for urban park design to improve user satisfaction and social sustainability.
