Archaeologists have discovered four ancient Cham kilns dating from the second to third centuries during an emergency excavation at Chau Sa Citadel in Tinh Khe Commune, Quang Ngai Province.
The discovery followed a report from a local resident who uncovered traces of an ancient kiln while digging a hole to plant a tree.

Speaking on July 20, Doan Ngoc Khoi, deputy director of the Quang Ngai Provincial Museum, said the emergency excavation confirmed the presence of four remarkably well-preserved oval-shaped kilns built by the Cham civilisation.
Archaeologists excavated two trenches covering approximately 100 square metres, revealing kilns measuring around 3.5 metres in length and one metre in width.
The excavation team also uncovered a large waste deposit containing roof tiles, gravel and charcoal surrounding the kilns.
Researchers believe the findings indicate that Chau Sa Citadel once housed a major Cham production complex where roofing tiles were manufactured for temples, palaces and other monumental structures.
Khoi said the discovery represents an important piece of evidence that will help archaeologists better understand the history and significance of the ancient citadel.
Built before the 10th century, Chau Sa Citadel is regarded as the only surviving earthen citadel constructed by the ancient Cham people. The site consists of an inner and outer enclosure, strategically positioned against natural mountain ranges and connected to an inland waterway network.
The Ministry of Culture, Sports and Tourism recognised Chau Sa Citadel as a national historical and cultural relic in 1994.
