Ancient Cham well from the 12th century has been unearthed.

To date, the newly unearthed square well opening, measuring approximately 1 x 1 meter, was constructed using a method similar to Cham towers, without mortar joints, and using Cham bricks...

On May 6th, the Department of Culture, Sports and Tourism of Quang Nam province sent a document requesting the authorities of Huong An commune (Que Son district) to take measures to demarcate the area around the ancient Cham well recently unearthed in Huong Que village ( photo ), and to expand the protection zone so that specialized agencies can continue to research, excavate, and determine the value of the relic.

Mr. Ton That Huong, Head of the Cultural Heritage Department (Quang Nam Provincial Department of Culture, Sports and Tourism), said that the elders in Huong Que village confirmed the existence of an ancient well in what is now Hamlet 6, Huong An commune, but it was filled in after 1975.

To date, the newly unearthed square well opening, measuring approximately 1 x 1 meter, was constructed using a method similar to Cham towers, without mortar joints, and using Cham bricks...

Notably, this site lacks Vietnamese elements (additional construction during use) unlike many other ancient Cham wells in Hoi An, Cu Lao Cham, Nui Thanh, etc.

Initially, experts estimated that this ancient well dates back to around the 12th century, the same period as the Huong Que Cham ruins located about 20 meters away; the Huong Que ruins now only contain a few artifacts such as steles, statues of sacred bulls, and reliefs of dancing women.
