7. Wat Arun (Thailand)
Bangkok’s relentless riverside development is beginning to threaten the iconic Wat Arun, or Temple of Dawn. Pollution from increased river traffic, encroachment by modern buildings, and constant vibrations from nearby construction all place stress on this historic site. These pressures risk undermining both the temple’s structural stability and its visual prominence along the Chao Phraya River. Preserving Wat Arun requires careful oversight as Bangkok’s cityscape continues to transform at a rapid pace.
