Only 500km to the West of Hanoi, the battle ground in Dien Bien Phu is a well-known site marking a victorious exploit of Vietnamese people in the Indochina War. It is located in a valley, surrounded by mountains, hills and paddy fields. The valley has a length of 20km and a width of 6km. All year round, the mighty Nam Ron River provides it with fresh water. Realizing the strategic position of this land, in 1953, the French decided to turn it into a military headquarters and equip it with the most powerful weapons at that time.
