A significant religious site for Chai Nat ever since its construction during the Ayutthaya period, this hillside temple is located on the bank of the Chao Phraya River, 8 kilometers from Chai Nat town proper. It enshrines Luang Pho Thammachak, a standing Buddha image with a mixture of the Sukhothai and Ayutthaya styles. The center of the image’s right palm features the Dharmachakra, or Wheel of Doctrine. Fairs to worship Luang Pho Thammachak are held twice a year during the 4th to 8 th day of the waxing moon of the sixth lunar month, and 4th – 8 th day of the waning moon of the eleventh lunar month. Another attraction is a boundary marker, made from red sandstone in the Ayutthaya style, near the ordination hall or PhraUbosot.
The temple is located in TambonThammamun, about 8 kilometers from AmphoeMueang. It is situated on Highway No. 1 at Km. 288 - 289 and is accessible through Thunmanukun School.
