Gio An ancient well (Gio An commune, Gio Linh district) is a structure to provide water for daily life and production. It is a relic of unique archaeological, cultural, and artistic value created by the ancient Cham people. It was received and preserved by the Vietnamese to this day. Gio An ancient well was dug at the end of the Neolithic Age, about 5000 years ago. The well is unique for its multi-component structure. It was built from various pieces of rocks, which were arranged meticulously. This is a technique of exploiting water with a unique structure, showing the skillful stone arrangement of the ancient Cham people. Water flowing all year round from local natural groundwater springs is used to serve life./.
