Hue City is the urban area with the highest density of trees in the country, with more than 64,000 trees lining its streets, parks, and lush green garden houses. These trees are cared for and protected by both local authorities and residents, beautifying the city while serving as a natural shield that brings a refreshing sense of coolness during the scorching summer heat.

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.
