Thammamul Worawihan Temple stands as a prominent royal temple nestled at the foot of Thammamul Hill, gracefully bordering the Chao Phraya River. It enshrines Luang Pho Thammachak, a highly revered Buddha image depicted in the Preventing the Ocean posture. This sacred statue is uniquely distinguished by the Dhamma Wheel symbol emblazoned on its palm, a significant emblem for Chainat Province. The temple grounds provide a tranquil and shaded environment, complete with a staircase leading to the hilltop, offering breathtaking panoramic vistas of the river's curve. A visit to Thammamul Worawihan Temple provides a profound connection to one of the most ancient spiritual and historical foundations in the central river basin region.
