Wat Thammamun Worawihan

Wat Thammamun Worawihan is a historic Buddhist royal temple (Worawihan) located on Thammamun Hill on the east bank of the Chao Phraya River in Tambon Thammamun, Mueang Chai Nat District, Chai Nat Province. It is notable for enshrining Luang Pho Thammachak, a highly revered ancient Buddha image, and for its hilltop location offering river views. Dating to the Ayutthaya period, it remains an important religious and cultural landmark of Chai Nat.

Visitors can expect a hilltop temple complex reached by a long naga-flanked stairway. The main vihara enshrines the large Luang Pho Thammachak Buddha image. The grounds include smaller shrines, chedis, and Buddha statues, with shaded courtyards and viewpoints overlooking the Chao Phraya River and surrounding plains. The setting is quiet and religious, with areas for worship, merit-making and photography.

Wat Thammamun Worawihan is believed to have been built during the Ayutthaya period and has been restored in later periods. It was later elevated to a royal temple of the Worawihan class. The temple is historically associated with the settlement on Thammamun Hill and preserves the ancient Luang Pho Thammachak Buddha image, an important object of local veneration for centuries.

The temple is a major Buddhist religious site for Chai Nat Province and central Thailand. Luang Pho Thammachak is highly revered by local Buddhists who visit to pay respect and make merit. The annual worship and merit-making traditions reflect the temple's role as a spiritual centre for the Thammamun community.
