In the depth of Hue culture, gardens are not merely green zones, acting as supporting elements for architecture, but a constituent factor shaping the urban identity. Hue is famous for the Perfume River, Mount Ngu, the Citadel, royal tombs, pagodas, and noble residences, but Hue is also well known for its gardens. In Hue, gardens soften architecture, calm the everyday life, deepen poetry, and create a unique urban style: a garden city, a city of poetry, the harmony between man and nature, or “an urban poem” as said by M’Bow, former Director-General of UNESCO.
