Around 25km north of Dong Van and just a few kilometers from the Chinese border, Lung Cu is a massive flag tower erected in 2010 to mark the northernmost point of Vietnam. It is modeled on the flag tower of Hanoi.
The flag tower shows the affirmation of position and sovereignty of Vietnam as well as honor the patriotism and bravery of the people and soldiers in the border area. The flag on the tower has an area of 54 square meters, representing the unity of 54 ethnic groups in Vietnam. This is a great place to take panoramic views of Dong Van, Ha Giang, especially the winding Happiness Road below.
The monument was built to mark the northernmost point in Vietnam, however, the farthest north point on the Chinese-Vietnamese border is located under Nho Que River, about 3km from Lung Cu Flag Tower, at Xeo Lung village.
Milestone 428 is not the northernmost point but the most Vietnam-China border landmark with the northernmost point, about 500m from Nho Que River along the flying way of birds. Nho Que is a common river of Vietnam and China, so it is also the boundary of the two countries.
North Pole Milestone is a symbolic northernmost point at Xeo Lung village, about 3km from Lung Cu Flag Tower. Up to now, this is the closest accessible point to the north pole of the country.
Standing on the Observatory (simulating One Pillar Pagoda), the view covers the boundary strip of the North Pole cone, where Nho Que River begins to flow into Vietnam.
