Historic urban areas are a crucial component of urban heritage, embodying the collective memory of urban development and possessing distinctive urban textures and cultural attributes. However, the growing impact of globalization on the urban environment poses challenges to historic urban areas, including diminishing social recognition, aging infrastructure, loss of vitality, and cultural erosion. To address these challenges, this study proposes a novel approach to revitalizing historic urban areas by employing space syntax methodology. The study focuses on Yushan Historic District in China as a case study and uses spatial models within space syntax to describe, analyze, and interpret its urban morphology. The objective is to enhance urban vitality while preserving the heritage fabric of historic urban areas. Additionally, it aims to contribute to the advancement of space syntax research, specifically in the context of urban renewal and revitalization of historic districts. The findings reveal the spatial factors that contribute to the generation of vitality within the district, identify areas requiring intervention, and provide strategies for revitalizing historic urban areas. This study demonstrates the potential of utilizing a space syntax approach in urban revitalization, providing valuable guidance for effectively conserving urban heritage within the context of urban renewal.
