Little remains of once was a vast supply and command center for the US/ARVN I Corps based along the southern edge of the DMZ. With the help of a local guide, we found one remaining concrete reinforced revetment that had probably been used by helicopter units. The revetment is totally surrounded by houses today - local woodworkers work inside. A monument is placed outside a breach in the concrete - a result of the successful NVA assault here in 1972. The revetment is similar in construction to the ones still in use at Da Nang, Hue - formerly the Phu Bai Airfield, and at Ton Son Nhat in Ho Chi Minh City. All the rest of the former base has been swallowed up in the new development of Dong Ha.
