Spatial justice, as a key concept in urban planning, emphasizes the equitable distribution of facilities and services across different urban areas and plays a crucial role in reducing social inequalities and enhancing the quality of life for citizens. Attention to spatial justice in the distribution of cultural centers, especially in developing cities, can facilitate sustainable development and strengthen social and cultural capital. This study examines and analyzes the spatial distribution of cultural centers in Zanjan city with an emphasis on spatial justice. Spatial data related to cultural centers were extracted from sources such as OpenStreetMap, Overpass Turbo, and Google Earth, and after refinement and classification, these centers were categorized into different groups. To analyze the spatial structure and distribution patterns, Moran’s I spatial autocorrelation index was employed using GIS software. The results indicate that the distribution of some cultural centers, such as mosques and language institutes, exhibits significant and concentrated clustering patterns, whereas other centers, including cinemas and art galleries, show dispersed and random distributions. This spatial inequality can adversely affect equitable access to cultural facilities. The study highlights the necessity of implementing distributive and procedural justice in urban planning to ensure a balanced distribution of cultural centers, thereby improving quality of life, reducing social gaps, and reinforcing cultural capital.
