Aluthnuwara Dedimunda Devalaya (shrine) is taken a significant importance among the Buddhist and Hindu people of Sri Lanka. It is also a popular tourist destination as it has an archeological value. Aluthnuwara Dedimunda devalaya is situated Kegalle district, Mawanella electorate near Hingula town. The devotees believe that the god Dedimunda is the guardian deity of the Buddha Sasana. The name Dedimunda denotes that he was firm, hardhearted and has strong and dominant personality. The devotees come many parts of the island to Devalaya to take blessing from the God Dedimunda for their various expectations. It can be observed that more devotees come to Devalaya on Kemmura days, Wednesdays and Saturdays, as blessings are powerful.
There is folklore that when King Parakramabahu II in Dambadeniya reign was passing through Aluthnuwara on his way to Sri Pada, he was very impressed with this place. He then decided to donate the property for his loving queen Giriwasa Sunethradevi, to the temple. Near to this period a monk had come to reside here from Galaturumula Viharaya in Devinuwara. The monk was known as Assaddana Pirivenhimi as he was the founder of the Assaddana Pirivena close to the temple. His successors reside at the present Kirthi Sri Raja Maha Viharaya. The King Parakramabahu II was taken very ill and found it difficult to speak. His chief minister Devapathi Raja visited Devinuwara and made blessings to God Upulvan for immediate recovery of the King. In a dream, the chief minister was informed that the king’s illness cannot be cured. He returned to Dambadeniya with the ornaments of the deity and informed the king of his strange experience. Eventually the King died. A deity had informed them to build a shrine for the God Upulvan. Accordingly, a shrine was built. A statue of God Upulvan was sculptured out of Sapu wood by a famous sculptor and the statue placed in the newly built shrine. The place where the Sapu tree stood came to be known as Sapugathtara. The ornaments of the deity were brought from Devinuwara and deposited in the Devale at Aluthnuwara. Buildings were added on to the Devalaya during the reign of King Panditha Parakramabahu IV. The place was known as Nawatilakapuraya and later it became Aluthnuwara. There is another belief that a chieftain was defied as Devatha Bandara after his death and was also the chief minister of god Upulvan. A small Devalaya (shrine) was built in close proximity to the main Devalaya. Upto the time King Wimaladharmasuriya I of Kandy, kings and chieftains donated lands and other valuable items to maintain the Devalaya. When the Portuguese invaded Kandy they looted the Devalaya on their way. Hence, for safety the image of the God Upulvan was brought to the Sri Dalada Maligawa during King Senarat’s reign. At this time Hindu beliefs and worship became popular. Thus, Upulvan Devalaya in Kandy came to be known as Maha Vishnu Devalaya. With the shifting of the Upulvan Devalaya to Kandy, now only the Dedimunda Devalaya remains at Aluthnuwara.
