Luang Phor Phet is a Maravijaya Buddha image in the Chiang Saen (Singha 1) style, dating back over 800 years. Legend has it that the image was cast during the height of the Chiang Saen Kingdom. During the Ayutthaya period, when Phraya Khotrabong founded the city of Phichit, the image was invited from the north to serve as the city's principal Buddha image. After being housed at Wat Nakhon Chum for a time, it was moved to Wat Tha Luang in 1899 by Phra Thammathassimuniwong (Iam), then the ecclesiastical provincial Governor of Phichit, where it remains a central object of devotion today.
