evidence: Another famous historic cave is ‘Pahiyangala’ (Fa-Hien cave), which is situated in the district of Kalutara. Evidence suggests that this massive cave was inhabited by troglodytes some 37000 years ago and is supposed to be the most ancient historic human settlement in Asia. [...] The Ravana cave lies 1370m above the sea level on the foundation of a cliff. It is 50ft wide, 150ft long and 60ft in height. Inside it is pitch-dark. We are allowed to walk only up to 200m of it, and moving beyond that could be a bit risky due to the wild animals and poisonous snakes. Inside the cave there are a few other large cavities. If we have a closer look at the rock wall surface we can see an imprint of a big demonic face on it. Apart from that, a few other similar scary imprints can be found. [...] The cave is a legendary historical site that is archaeologically important. The excavations carried out by the Department of Archaeology at the site have revealed a lot. Ten skeletal remains that were unearthed here were thought to be belonging to cannibalistic Balangoda Man (Homa sapiens balangodenis), and according to those findings, there had been human habitation dating back to 25000 years.
