Sense of place (SOP) has recently been considered an effective strategy through which to pursue sustainable place development. However, many urban spaces have not usually considered the contribution of built-environment factors to SOP and SOP’s contribution to people’s willingness to revisit for sustainable place. Therefore, this research aims to understand the internal structure of SOP at Daehak-ro, one of the most famous cultural district and tourism sites in Seoul, Korea. Through this study, the sociocultural factor was found to make the greatest contribution to Daehak-ro’s SOP, and SOP was itself found to be highly related to willingness to revisit. These results suggest that non-physical factors could be most important to developing an SOP in urban environments. This study will eventually lead to better understanding of developing SOP, and will contribute to Daehak-ro becoming more sustainable than at present.
