Lung Cu Flag Tower

Lung Cu Flag Tower is a national monument atop Dragon Mountain in Lung Cu Commune, Dong Van District, Tuyen Quang Province, near Vietnam's northern border with China. Standing about 33 meters high with a 54-square-meter flag representing Vietnam's 54 ethnic groups, it marks the country's northernmost landmark. Rebuilt in 2010 on the site of earlier flag towers, it offers panoramic views of the Dong Van Karst Plateau Geopark and surrounding villages.

Visitors can expect a climb of approximately 839 stone steps to the base of the tower on Dragon Mountain, followed by a spiral staircase of 135 steps inside the tower to the viewing platform. At the top, a large Vietnamese flag flies above a panoramic landscape of terraced fields, karst mountains, and villages near the border. The site includes a memorial area, exhibition space about the tower's history, souvenir shops and photo spots with border markers.

The site has hosted flag towers since the Ly Dynasty, with later versions during the Nguyen Dynasty and French period. The current tower was inaugurated in 2010, built to a design modeled on Hanoi Flag Tower, standing 33.15 meters high on a peak about 1,470 meters above sea level, commemorating national sovereignty at the northern frontier.

The tower is a national symbol of unity, with its 54-square-meter flag representing Vietnam's 54 ethnic groups. It is a prominent patriotic and cultural landmark for domestic visitors and an iconic stop within the Dong Van Karst Plateau Geopark, reflecting local ethnic minority heritage of the surrounding Lung Cu villages.
