via Vietnam Express, 05 November 2022: The 19th century gate marks the border between Thua Thien-Hue and Da Nang.
After a year of renovation, the Hai Van Gate in central Vietnam, abandoned for years, is gradually being returned to its original shape as a ‘defensive citadel’ under the Nguyen Dynasty.
Standing on top of the Hai Van Pass that separates Thua Thien-Hue Province and Da Nang City, the Hai Van Gate is about 490 meters above the sea level.
It was constructed in 1826 during the reign of King Minh Mang (1791-1841), who ordered the construction of several defensive structures along the pass to protect the imperial capital of Hue. The structures included fortifications, store houses and cannon forts.
