Hien Luong Bridge (Ben Hai River)

Originally built in 1928 by the French administration over the Ben Hai River. Under the 1954 Geneva Accords, the river at the 17th parallel became the temporary demarcation line and Demilitarized Zone dividing northern and southern Vietnam until reunification in 1975. The bridge was painted in two different colors on each side and became a symbol of division, with flag competitions, loudspeaker propaganda exchanges, and border guard posts. Destroyed by bombing and rebuilt several times, the current bridge is a reconstruction preserved as a national historic relic.

Considered a national symbol of reunification and resilience, the site is preserved as a Special National Historic Relic. It serves as a memorial and educational site commemorating the period of division and reunification, with annual commemorative activities and a museum that presents the cultural memory of the Ben Hai River area for domestic and international visitors.
