Ridi Viharaya, also known as the Silver Temple, is a Theravada Buddhist temple situated in the village of Ridigama, Sri Lanka, dating back to the 2nd century BCE. It was constructed during the reign of Dutthagamani of Anuradhapura. This historical site holds significance as it is believed to be the location where the silver ore necessary for the completion of Ruwanwelisaya, one of Sri Lanka’s largest stupas, was discovered. According to ancient chronicles such as the Mahavamsa and Thupavamsa, the construction of the Ridi Viharaya complex was an expression of gratitude towards the divine forces for assisting Dutthagamani in realizing his vision of completing Ruwanwelisaya.
