Collision of tradition and visual perception: aesthetic evaluation and conservation intent in adapting traditional Chinese gates within architectural heritage

The sustainable conservation of architectural heritage has attracted significant attention, especially with the rapid development of heritage tourism. Adaptation is a compromise to allow heritage to meet modern development demands; however, unregulated adaptations pose significant risks to sustainable conservation. This study involved 60 participants in a quasi-experimental investigation, using eye-tracking technology combined with evaluation questionnaires. The aim was to explore how material, ornament, and generational age differences impact aesthetic evaluation, visual attention, and conservation intention toward traditional Chinese architectural gates. The results show a general preference for traditional materials (wood) and intricate ornament (Ice Crack), with participants displaying a stronger conservation intention toward these elements. Notably, generational differences were evident, with older participants showing longer visual engagement with architectural heritage design elements. This study extends aesthetic response theory into the heritage domain, emphasizing material authenticity and design complexity in shaping conservation attitudes. It offers valuable insights for heritage adaptation strategies, emphasizing the need to balance historical authenticity with aesthetic appeal to enhance public engagement.
