Not only are the things we find in caves amusingly beautiful, but sometimes the caves themselves turn out to be amazing also. The Karst Caves in China is one such cave that is irresistibly astonishing. This is because the walls reflect a color of blue and purple and how often do we find a cave with such beautiful walls.

The history of the walls suggests that it was created by some ancient river around 500,000 years ago. We’ve also come to know that this particular cave was used as a bomb shelter in WWII.
