Wat Uposatharam

Wat Uposatharam, also known as Wat Bot, is a historic Buddhist temple on the Sakae Krang River in Uthai Mai, Mueang Uthai Thani, Uthai Thani Province. Notable for its well-preserved early Rattanakosin-period murals inside the ubosot, the temple reflects late Ayutthaya to early Bangkok artistic styles. Its riverside location, traditional architecture, and active religious role make it a key cultural landmark in Uthai Thani's old town area.

Visitors can expect a compact riverside temple compound centered on the ubosot (ordination hall) housing extensive wall murals depicting Jataka tales and Buddhist cosmology. The hall features traditional Thai architecture with wooden and masonry elements. The grounds are quiet and shaded, located directly on the Sakae Krang River with views of traditional raft houses. Visitors can walk around the ubosot, view the murals inside when open, observe merit-making activities, and explore the small courtyard area.

Wat Uposatharam is believed to have been established in the late Ayutthaya period and restored in the early Rattanakosin period during the reign of King Rama I. The ubosot and its mural paintings date primarily to the early Rattanakosin era, with murals attributed to the reign of King Rama III, representing an important example of traditional Thai mural art and temple architecture of that period.

The temple is an active Theravada Buddhist temple and an important cultural landmark for Uthai Thani. Its murals are regarded as significant examples of Thai Buddhist art depicting Jataka stories and religious cosmology, and the temple continues to serve the local community for religious ceremonies and merit-making.
