1. Introduction to Lung Cu Flag Tower
Lung Cu Flag, one of Vietnam’s most sacred national symbols, is located on Dragon Mountain (Long Son) at an altitude of approximately 1,470 meters above sea level. It belongs to Lung Cu Commune, Dong Van District, Ha Giang Province, Vietnam (now administratively part of Tuyen Quang Province after the recent merger).
From the top of Lung Cu Flag Tower, visitors can admire two perennial ponds known as the “Dragon’s Eyes,” which never run dry and provide an essential water source for local ethnic communities. The site is about 24 kilometers from the former Dong Van town center and approximately 154 kilometers from Ha Giang Ward 2, Tuyen Quang Province. Today, lung cu flag is considered a must-visit check-in destination on any journey to explore the majestic Dong Van Karst Plateau.

Renowned Vietnamese writer Nguyen Tuan once poetically referred to Lung Cu Flag as “the northernmost point,” where the very first stroke is drawn on the S-shaped map of Vietnam. With its profound symbolic meaning, conquering lung cu flag is not merely a Ha Giang travel experience, but a deeply emotional journey that awakens national pride in every Vietnamese heart.
2. The History of Lung Cu Flag Tower
The Lung Cu Flag Tower has witnessed many historical periods and continuously evolved alongside Vietnam’s development. In its earliest days, the flagpole was constructed from wood, later replaced by iron. By the year 1202, it was rebuilt in a more solid form. In 1887, during the French colonial period, the structure was reconstructed once again.
Entering the 20th century, the tower underwent several major renovations. A significant milestone came in 1978, when the Dong Van District People’s Committee rebuilt the flag tower at a greater height and raised a national flag measuring 54 square meters, symbolizing the 54 ethnic groups of Vietnam. From August 12, 1978, the red flag with a yellow star began flying proudly atop Lung Cu Mountain, becoming a sacred symbol at the northernmost point of the country. Further renovations followed in 1992 and 2000, each expanding the scale of the monument.
In the early 21st century, a new version of the tower was constructed in 2002, standing approximately 20 meters tall. Its hexagonal base was decorated with Dong Son bronze drum patterns, while a 9-meter flagpole above carried the iconic lung cu flag measuring 54 square meters.

In early 2010, under the direction of the Vietnamese Government, the old tower was dismantled to make way for a more monumental structure. The current Lung Cu Flag Tower stands 33.15 meters high, with a 20.25-meter base and an octagonal shaft measuring 3.8 meters in diameter. The base is adorned with eight blue-stone reliefs inspired by Dong Son drum motifs, vividly depicting the history, culture, and daily life of ethnic communities in Ha Giang.
Inside the tower, a spiral staircase of 140 steps leads visitors to the top, where the lung cu flag flies majestically against the vast northern sky. After seven months of construction, the new tower was officially inaugurated on September 25, 2010.
Today, the Lung Cu Flag Tower is not only a powerful symbol of Vietnam’s sovereignty but also a must-visit destination in Ha Giang Province. The route to the summit features 839 stone steps, making the climb more accessible for visitors. From the top, travelers can admire the breathtaking mountain landscapes and gaze upon two emerald-green lakes at the foot of the mountain, affectionately known by locals as the “Dragon’s Eyes.”
At the base of the mountain, a memorial house displays cultural artifacts, traditional costumes, and farming tools of Ha Giang’s ethnic minorities, offering visitors a deeper and more meaningful cultural experience.
