Hoi An Ancient Town heritage preservation

Discussions regarding the sustainable development of Hoi An Ancient Town have highlighted the tension between tourism growth and heritage preservation. Experts have identified significant challenges, including overcrowding, environmental pressure, and climate change.

A primary concern is the demographic shift within the core heritage area, where the resident population has declined significantly. Reports indicate that approximately 40% of original residents have moved away, and roughly 30% of property owners in the core zone now reside in other major cities. This trend of residents renting ancestral homes for commercial use has led to warnings of “cultural hollowing” and a loss of authenticity.

Recent findings from a 2026 survey by the Hoi An World Cultural Heritage Conservation Center indicate that the physical integrity of the town is also under threat. The survey identified 28 heritage sites experiencing degradation, with 10 classified as severely degraded and 13 as heavily degraded.

Structural issues include leaking yin-yang tile roofs, termite damage to wooden components, rotting beams, and cracked or leaning walls, particularly along Nguyen Thai Hoc, Bach Dang, and Phan Chau Trinh streets. Nine specific cases have been proposed for dismantling because they no longer possess the structural integrity to support themselves. Notable risks include a house on Nguyen Thai Hoc street at high risk of collapse and a structure on Phan Chau Trinh street with an eastern wall that has tilted approximately 0.2 meters. These findings underscore an urgent need for safety measures and preservation efforts to protect both residents and historical integrity.
