Phra Phutthasihing is housed in the Phra Phuttha Sihing hall near the Provincial Hall. This sacred image was believed to have been ordered by the king of Lanka in 157 AD and was brought to Thailand during the reign of King Ramkhamhaeng the Great. There are currently 3 similar images in Thailand. One is housed at the National Museum in Bangkok, another at Wat Phra Sing in Chiang Mai and this image in Nakhon Si Thammarat. The hall housing the image was originally the Buddha image hall of the palace of Chao Phraya Nakhon (Noi). The hall is divided into 2 parts; the front portion houses Phra Phuttha Sihing, Phra Lak Ngoen and Phra Lak Thong and the back portion houses the ashes of the ancestors of the Na Nakhon family.
