Enhancing cultural heritage accessibility through space syntax: a case study of the archaeological site of the wooden water gate of southern Yue State

The accessibility of heritage sites is essential for sustaining cultural vitality in urban environments. This study investigates the Wooden Water Gate of the Southern Yue State in Guangzhou, China, with the goal of improving its spatial accessibility and integration within the historic district. Using an integrated framework combining Space Syntax analysis, field surveys, and urban design strategies, spatial metrics such as connectivity, integration, choice, and total depth were evaluated to diagnose accessibility challenges. The analysis revealed fragmented spatial structures, weak topological connections, and excessive spatial depth that hinder visitor movement and disrupt historical continuity. Based on these findings, targeted interventions were proposed, including enhancing pedestrian linkages, activating public spaces, and creating a cultural heritage experience loop. The results demonstrate that combining spatial analysis with urban design offers an effective approach to optimizing heritage accessibility. While grounded in a case, the insights contribute to broader applications for heritage revitalization globally.
