KATHMANDU, NEPAL, May 14, 2008: A 1600-year old temple in Nepal, considered the country’s oldest monumental site is facing a grave threat to its existence as the valley surrounding it witnesses continuous soil erosion and landslide. The Changu Narayan temple, which is located in Kathmandu valley, some 12 km east of Kathmandu, is on the agenda of a team of researchers from Kiel University who are conducting research into the deteriorating environmental condition of the area. “The surrounding area of the hill where Temple Changu Narayan is situated will collapse if the landslide and soil erosion are allowed to continue,” warned German archaeologist and Professor at the Kiel University of Germany Hans R Bork.
“The monumental area spreading in 36 hectares of land is facing soil erosion, landslide, deforestation and other man made environmental problems,” said Pradhan. Planting of more trees, construction of scientific pavements and a curb on animal gazing, besides creating awareness about the importance of the monument were the immediate steps needed to save the World Heritage site, he suggested.
He said the pottery, bricks and charcoal recovered from the site was being studied and some samples will be taken to Germany for laboratory tests to determine the exact date and history of the monumental site.
