When one hears "Nagadeepa Viharaya," the immediate association often tends to be with the Nagadeepaya in Jaffna. However, tucked away within the depths of Uraniya village in the Badulla District lies another significant site – the ruins of an ancient, yet unexplored temple complex known as the Nagadeepa Viharaya. Revered for its mystical and supernatural powers by local villagers, this hidden gem holds a special place in folklore and community beliefs. Despite its obscurity, this ancient site stands as a testament to the rich cultural and religious heritage of the region, awaiting further exploration and discovery. The area is known for its mystical and supernatural powers, and the temple is believed to be associated with ancient Naga (Cobra) tribes.

The temple's history dates back to ancient times, with folklore suggesting connections to King Dutugemunu's era. Ruins of the temple complex include two stupas and various buildings, indicating its antiquity. Inscriptions found on the premises date back to the 6th to 10th centuries AD, adding to its historical importance.

According to folklore, the Nagadeepa Viharaya's history is believed to stretch back to the reign of King Dutugemunu, who used the area as a camping and training ground for his armies. It's said that he made a vow at this location before going to war with King Elara. 

While no comprehensive archaeological survey has been conducted on the ruins, inscriptions discovered at the site suggest that its antiquity could be traced back to the 6th to 7th centuries AD. Pillar inscriptions and slab inscriptions dating to the 9th to 10th centuries AD have also been found on the temple premises, indicating its continued significance over centuries.

The Nagadeepa Viharaya consists of ruins of two stupas and numerous buildings. The smaller stupa, believed to have been built by King Dutugemunu, is fairly preserved up to the Devatha Kotuwa. Above this stupa is a massive stupa, now seen as an overgrown mound of earth. At the top of this mound is an old image house.

The site is now looked after by a single monk, who reportedly has the ability to confront dark forces in the area. The Archaeological Department has declared the Ridimaliyadda Nagadeepa Viharaya as a protected monument, recognizing its historical and cultural significance.
