For generations, the monument was popularly known as “Elara Sohona”, believed to be the tomb of King Elara (Ellalan). According to the traditional story, after defeating Elara, King Dutugemunu respected his fallen opponent and had a monument constructed for him.
During excavations at Dakkhina Stupa in the late 1940s, archaeologists recovered ash/charcoal material from the structure. It was later kept in the Archaeological Museum.
Then, in 1978, the material was taken for further examination, and a committee of 12 specialists was appointed to investigate whether it could be the remains of King Dutugemunu. After several months of investigation, the committee reportedly concluded that the ashes could be identified as those of King Dutugemunu.
The Mahavamsa tradition associates Dakkhina Vihara with Uttiya, a commander/minister during the reign of King Valagamba. Later kings renovated and enlarged the stupa.
