The history of this temple expands to Anuradhapura era. During the period of king Dutugamunu this temple has been built by the giant Pussadeva. The giant Pussadeva is one of the great ten giants (Dasamahayodayo), who was awarded a Gamvara by the king after the war. That was the Pallebedda Gamvara. Later the giant Pussadeva built a temple in Pallebedda and offered it to Buddha shasana, which is Sankapala Viharaya. This history has been revealed by a stone pillar erected in the temple.
Later during the Kandian era a Buddhist monk named Karathota Dhammarama was offered with this temple. That was during the period of king Rajadhi Rajasinghe. But due to a dispute aroused between the king and the monk, the monk was taken into custody and kept under house arrest. At that time the monk Karathota Dhammarama wrote a 'Harasa Kawya' (a peice of poetry which includes 12 poems in one poem which is written in a circular shape) to show his intelligence. Afterwards king begun to respect the monk evenmore and monk was offered the Gamvara again by the king.
This temple includes a Sathsathi Vihara Mandira which has two Buddha statues in sitting posture and an ancient Buddha statue in standing posture. All of these statues have similarities to the statues of Kandian era. And the paintings on walls of the Viharaya, which were painted with indigenous material, also resembles Kandian era.
Apart from Sathsathi vihara mandiraya there is another shrine room in the middle of the temple, which is called 'Maha Viharaya'. This shrine room also consists of several Buddha statues as well as two statues of God Katharagama and God Vishnu.
This is an ancient temple, which should be preserved and which must be seen by you despite religious differences.-Dilan Dharshana
