It is a suburb of Galle, about 5 kilometres (3.1 mi) southeast to the city center and approximately 108 kilometres (67 mi) south of Colombo.

PUnawatuna traces its roots to the great epic Ramayana. In the epic, the monkey-warrior Hanuman was sent back to India to fetch the four medicinal herbs by Jambavan namely, mritasanjeevani, vishalyakarani, suvarnakarani, and sandhani from the Himalayas in order to heal Lakshman who was wounded trying to save the abducted Princess Sita from the demon king Ravana. Hanuman failed to identify these herbs, so he lifted the entire mountain and carried it to the battlefield to try to save Lakshman, but in the process, a chunk of it "fell-down" in the location of the present day Unawatuna, the name of the village derives from "Una-watuna" meaning "fell down".
