Fa Hien Cave

Fa Hien Cave, Faxian Cave, or Pahiyangala Cave is situated in the district of Kalutara, Western Province, Sri Lanka and according to a rural legend, named after an alleged resident during historical times, namely Buddhist monk Faxian, previously romanized as Fa Hien. However, there is no archaeological or historical evidence to support this legend. Nonetheless, the site is of archaeological significance as Late Pleistocene human fossilized skeletal remains were discovered in the cave's sediments during excavations in the 1960s, the 1980s and in 2013.

This is the largest natural stone cave in South Asia. 3500 people can stay here at the same time. To see the size of the cave, you have to go inside and look outside. Prehistoric humans have lived here for 35000–60000 years. They used sea fish, salt, and shark teeth as ornaments. This limestone was formed by corrosion over hundreds of thousands of years.
