The Hai Van Gate (Hai Van Quan) was built on Hai Van Pass by the Nguyen dynasty in 1826 to protect the Hue Imperial Citadel and control Da Nang’s waterfront. The structure was recognized as a national relic site in 2017 and is now being renovated as a tourist attraction. Hai Van Gate Located 490 m above sea level, the Hai Van Gate holds profound historical, architectural and artistic value. It connects Da Nang City with Thua Thien-Hue province in the central region. Structures include fortifications, store houses, and cannon forts. A recent excavation of the Hai Van Gate relic complex unveiled the layout of the old citadel walls and a section of the north-south route. “The Hai Van Gate’s position was of strategic importance to national defense during the Nguyen dynasty. It helped protect the Hue imperial city, which has been recognized as a world heritage. Accommodations for tourists need to be built while infrastructure should be upgraded to support tourism development,” said Dr. Do Bang, President of Thua Thien-Hue Historical Sciences Association.
