Local architectural heritage is often marginalized in education due to its small scale, indistinct features, or incomplete preservation. This study uses the XinBeishi East Gate as a case to explore how such undervalued heritage can be integrated into junior high school education through an art-based approach, especially given the lack of formal cultural heritage teacher training at this level. The research focuses on six village gateways in Liudui—four officially registered and two unlisted—to examine how visual arts education can support students’ understanding of heritage value through comparative analysis, observation, and creative engagement. Findings reveal that visual arts education not only fosters aesthetic awareness and expression but also enables interdisciplinary learning and sociocultural interpretation. Despite belonging to the same regional system, the gateways exhibit distinct stylistic and decorative features, reflecting both cultural diversity and environmental adaptation. Through fieldwork and community interaction, students developed a deeper sense of connection between heritage preservation and local identity. This study highlights the educational potential of integrating local cultural assets into art curricula to enhance place-based awareness and heritage literacy.
