Originally known as Wat Ratchasing, this temple has historic roots in the fierce Thai elephant duel. According to folklore, King Naresuan the Great commissioned the temple following his legendary victory over the Burmese viceroy, Phra Maha Upparacha, in a much-storied elephant duel. His sister, Phra Suphankanlaya, who had been taken hostage in Burma, was later executed in revenge. As a result, King Naresuan the Great dedicated the merit earned from the construction of the temple to his late sister. The temple’s principal Buddha image, known as Luang Pho Dam, dates back 500 year and is depicted in the posture of subduing Mara with a lotus bud halo. Within the temple compound, the public can pay their respects to the three royal sibling statues: King Naresuan the Great, King Ekathotsarot, and Phra Suphankanlaya. The temple is located in Tambon Ban Sa.
