The site is now on the list to be recommended to UNESCO for recognition as a World Heritage Site.
Tien Son Grotto was discovered in April 1935 in the limestone mountain
of Ke Bang. It is about 400m away from the famous Phong Nha Grotto and
at a height of 135m. Tien Son Grotto is more than 980m long. Going into the cave for about
400m, visitors will see an abyss, about 10m deep. Then comes another
part of the cave, about 500m long is rather dangerous for walking. At
present, nearly 400m of the cave have been installed with lighting
system to make it safe for visitors.
Some look like a man or an animal, and there is one that looks like the
Learning Tower of Pisa in Italy. On the cave ceiling, there are
glittering gold and silver-like veins. Some stalagmites produce an
echoing sound when slightly knocked.
Limber Howard, Chief of the British Royal Team of Cave Researchers, who
visited and made studies of the site, said that Tien Son Grotto may
have been formed tens of millions of years ago. A river ran through the
limestone mountain and eroded it. Then huge rocks fell, separated the
mountain and form the cave. An under ground river ran through the lower
part of the mountain, creating Phong Nha Grotto. Thus, Tien Son Grotto
is older than Phong Nha Grotto and they do not link with each other.
Geographical tectonics in Tien Son Grotto is rather stable.
