Located in Xuan Vien Commune, Nghi Xuan District, the site was first discovered and excavated in the 1970s by experts from the History Department of the Hanoi General University, who said the site was dated back to the later Neolithic period.

The second excavations in 2008 further revealed that this is a site of tombs, belonging to the culture of Sa Huynh, which lasts from the beginning of the Christian era until the second century AD. There is also evidence that the site witnessed interactions between the Sa Huynh culture and the culture of Dong Son further north.

In addition to jar-tombs, which are typical of the culture of Sa Huynh, many earth tombs typical of the culture of Dong Son have been found in large number at the site.

The influence of the culture of Dong Son was also seen through artefacts found at the site, such as various types of axe with typical features of the culture of Dong Son such as spread blade or rectangular axes. The latest excavation work will be conducted on an area of 200m² and will complete in the middle of April next year. The excavation is aimed at digging further deep into prominent characters that prove the intertwinement and mutual influence between the culture of Sa Huynh and the culture of Dong Son in the site.
