What is "belilena"

Belilena is a famous large cave in Sri Lanka. It is located 8 km from the town of Kitulgala. It holds evidence of a lost generation of Sri Lankans some 12,000 years old; at this time the cave was occupied by Balangoda Man, described as Homo sapiens balangodensis by Paul E. P. Deraniyagala, who found ten skeletons of these people. They lived 2,000 feet above sea level. It is believed they lived more than 32,000 years ago.

A visit requires a rope or rope ladder for entry. The part of the cave beyond the lake that fills it a short way from its mouth still remains unexplored.
