Thien Canh Son Cave History

The landscape of Ha Long Bay was entirely different millions of years ago. Instead of tall limestone pinnacles, it was covered by vast seawater. The seabed rose due to the movement of tectonic plates over a very long period, exposing the underlying limestone to the harsh weathering processes. Water saturated with mild carbonic acid permeated through cracks and fissures in the limestone rock and began its slow journey towards the earth’s centre, carrying away calcium carbonate present in huge quantities. There occurred a change in conditions, causing the deposition of dissolved calcium carbonate and leading to the formation of stalactites hanging from the ceiling like gigantic teeth.

In some cases, drops fell on the cave floor, forming stalagmites that grew into enormous columns with time. This process has been going on for thousands of years, giving rise to magnificent structures inside Thien Canh Son Cave. The different forms and sizes of these stalactites and stalagmites show natural forces of creativity with time. Although it cannot be proven true or false, they add mystery to Thien Canh Son Cave.
