1. Where is the Hien Luong Demarcation Flagpole?
Hien Luong Flagpole, also known as Hien Luong Flag Tower, is located on the north bank of the Ben Hai River in Hien Thanh Commune, Quang Tri Province. This is one of the prominent features of the Hien Luong – Ben Hai River Banks Special National Historical Relic Site, a complex associated with an important historical milestone of the nation during the period of division.
Located right next to Hien Luong Bridge on National Route 1A, about 60 km north of Dong Ha city center, Hien Luong Flagpole occupies a unique position along the historic Ben Hai River. During the war years, it stood as a symbol of the will and aspiration for national reunification shared by the people of both North and South. Today, the site not only carries deep historical value but also serves as a meaningful destination, attracting numerous visitors exploring the famous historical sites of Quang Tri.

2. The history of the Hien Luong Flagpole associated with the 17th parallel
Following the 1954 Geneva Accords, the country was temporarily divided at the 17th parallel with the Ben Hai River serving as the military demarcation line. In this context, the Hien Luong Flagpole was erected on the north bank of the Ben Hai River as a symbol asserting sovereignty, expressing the determination to unify the country and steadfast faith toward the beloved South. In the early years, the flagpole was constructed from a casuarina tree standing about 12m high, proudly displaying the red flag with a yellow star in the demarcation zone. Over several upgrades, by 1962, the structure was rebuilt with steel to a height of 38.6m, becoming the tallest flagpole in the demarcation area at that time. The large national flag was designed to be visible from a great distance, becoming a powerful spiritual symbol for the military and people on both sides.
Throughout the fierce years of war, the Hien Luong Flagpole was damaged by bombs and artillery many times, yet it was repeatedly restored and defended. The image of the red flag with a yellow star fluttering in the sky above the demarcation line became an enduring symbol of patriotism, the desire for peace, and the Vietnamese nation's resolve to unify the homeland.

3. The legendary "flag battle" on the 17th parallel
One of the most notable stories surrounding the Hien Luong Flagpole was the "flag battle" between the North and South banks from 1954 to 1967. This was not merely a height competition but also a symbol of indomitable spirit and the aspiration for reunification.
Initial Phase (1954-1956): The South erected a 15-meter flagpole on the Xuan Hoa bunker. The North responded with an 18-meter pole.
Escalating Height: The contest became increasingly intense. By 1962, the South constructed a reinforced concrete flagpole 30 meters high. The Northern army and people quickly erected a new 38.6-meter pole featuring a flag measuring 134 m² and weighing 15 kg—making it the tallest flagpole along the demarcation line.
Destruction and Resilience: US aircraft launched airstrikes and destroyed the flagpole multiple times, but our forces re-erected it 246 times, continuously flying the red flag with a yellow star. The climax was an airstrike on August 2, 1967, which snapped the flagpole, but the very next night, our soldiers demolished the Southern flagpole.
The "flag battle" extended beyond height to include a "sound war" with loudspeaker systems on both banks broadcasting propaganda and boosting morale. Stories of local figures like Mr. Le Cong Huong—the flagpole guard—became symbols of the steadfast resilience of the Vinh Linh people.

4. What is special about the Hien Luong Flagpole today?
Today, the Hien Luong Flagpole has been restored and serves as the centerpiece of the Hien Luong – Ben Hai River Banks Special National Historical Relic Site, designated in 2013. The current flagpole stands 28m tall, constructed from steel tubing with a system of cables and winches, flying a red flag with a yellow star measuring 9.6x4m, modeling the original 38.6m pole.
Key features include:
Restored Hien Luong Bridge: Measuring 183.65m long and 5.5m wide, painted half blue (North bank) and half yellow (South bank) with a 1cm white line as the boundary line, recreating the image of division.
Exhibition House “17th Parallel and the Aspiration for Reunification”: Preserves 53 documents and artifacts regarding the Geneva Accords, the struggle, and the 500W loudspeakers.

Ferry piers: Such as Cua Tung and Tung Luat piers, featuring a monument shaped like a boat braving the waves.
