Scientists from the Centre for Southeast Asian Prehistory recently made the discovery during an on-going preservation project at the site.
"This is the first discovery of such an ancient road in the Southeast Asian region and a rare discovery in the world," Nguyen Viet, PhD, centre director told Viet Nam News.
The Xom Trai Cave represents a typical residence of the Hoa Binh civilisation (from 34,100 years ago until 2,000 BC) in the ancient Muong Vang region, which is today’s Tan Lap Commune, Lac Son District in Hoa Binh Province.
The cave was discovered in 1974 and went through various stages of excavation in 1981, 1982, 1986 and 2004. The Ministry of Culture, Sports and Tourism listed it as a national archaeological relic in 2005.
The Hoa Binh Museum has co-ordinated with the centre to preserve the relic since 2004. Since then, researchers have discovered traces of approximately six metres of a road at the south end of the cave’s mouth. The ancient pathway lies 60-70cm deeper than the Hoa Binh civilisation layer. The traces are believed to date back 8,000-9,000 years ago and remain in good preserved condition.(...)"
