Situated in the Ratnapura district belonging to the Atakalan Korale Thambagamu Pattu Pallebedda Village the Sankapala Raja Maha Viharaya lies in the outskirts of Ratnapura Hambantota main road near the 24th milepost. From here a distance of about 150 yds, is the rock mountain wherein the ruins of buildings, a Bo tree, a dagoba, and a cave Deralaya has been found.
Brahamin inscriptions cared beneath the dripledges ("Katarama" in Sinhalese) of the rock dating back to a period of even before the birth of Christ is ample evidence to prove the existence of a monastery.
Folklore has it that Pussa Deva a warrior of King Dutu Gemunu (161-131 BC) resided here. This is conformed by the fact that Pussa Devas name has been mentioned in the rock inscriptions. Pussa Deva who played a prominent part in King Dutugemunu's wars was well versed in the art of war and blowing the conch shell. Hence the emblem conch shell was used to identify him. Further it is mentioned that later-on in life he was ordained a monk and achieved the state of Rahath. However, owing to the evils of nature this abode had been later abandoned.
This place was resurrected again and made a popular place of worship by Venerable Karathota Dharmarama during the Kandyan period.
