Alongside preservation of palaces and temples, the heritage conservation efforts in the Ancient Capital also include the care, restoration, and propagation of trees, protecting ancient and precious species within relic sites, helping maintain the harmonious beauty of architecture and nature - a hallmark of Hue’s heritage space.

The lush lawns and shaded canopies of ancient trees in the Imperial Citadel, Co Ha Garden, or Thieu Phuong Garden are not naturally self-sustained. Behind that serene beauty lies the quiet dedication of dozens of workers who care daily for every tree and flowerbed, helping preserve the “green soul” of Hue’s heritage.
