Archaeologist Doan Ngoc Khoi from the Quang Ngai Museum said the 3m-long and 2m-wide kiln is located at the centre of the Chau Sa citadel, found in early 20th century by French architect Henri Parmentier – who had engaged in repairing and restoring various Cham towers in Vietnam.

Mr Khoi said the discovery of the kiln with wasted bricks showed that the existing Cham towers in Vietnam had been built with baked bricks instead of the current theory that they were built with unbaked bricks and then burnt.

The Quang Ngai Museum is asking for permission from the provincial People’s Committee and the Ministry of Culture, Sports and Tourism to further excavate the archaeological site.
