This system consists of 30 ancient wells, built by rock. Local people have water from these wells for their daily life. The Ministry of Culture, Sports and Tourism in 2001 recognized 14 wells as national monuments.

There are three types of wells, including gieng mang, gieng ao and bi. The people said water is fresh, warm in the winter and cool in the summer. Many people still draw water from the well for drinking.

Gieng mang consists of an infiltration pool at the top; water runs from here through two long conduits to a wide tank of 20-40 m2, one meter deep. Water in this tank is for people’s use. There is a small water tank for cattle and a canal for agriculture production.

Gieng ao contains only water for drinking.

Gieng bi was built by basalt monolith, 0.5 m in diameter. Each well has about 3-4 balls, more than a meter deep.

It is special that these wells take advantage of groundwater that has been flowing for thousand years. The system was created by indigenous Champa people from the first century AD.

This is a unique cultural heritage in Quang Tri, the evidence of ancient agricultural civilization of the Cham, showing clever behaviors to exploit the potential of nature.

Thanks to these wells, locals can grow many liet vegetables, making it a particular specialty here. 

During wars, many wells changed or were devastated. Quang Tri Monument Conservation Center is working to restore the wells.

In the future, Quang Tri province will seek a world heritage title for these wells.
