Phra That Nong Sam Muen

Phra That Nong Sam Muen is an ancient Buddhist stupa located in Ban Kaeng Subdistrict, Phu Khiao District, Chaiyaphum Province, northeastern Thailand. Believed to date to the Dvaravati period (7th-11th century CE) with later restorations, it is one of the most important archaeological sites in Chaiyaphum. The brick chedi enshrines Buddha relics and is revered by local Buddhists, set in an open plain near Nong Sam Muen reservoir.

Visitors can expect a historic brick stupa standing on a square laterite base in an open, rural setting surrounded by fields and the Nong Sam Muen reservoir. The site consists of the main chedi, remnants of ancient foundations, boundary markers, and a small modern shrine area. The environment is quiet and open-air with little shade. Visitors can walk around the stupa, view architectural details, pay respect, and take photographs.

Phra That Nong Sam Muen is attributed to the Dvaravati period (approximately 7th-11th century CE) and is considered one of the oldest Buddhist monuments in Chaiyaphum. Constructed of brick on a laterite base, the stupa shows Dvaravati architectural influence and was later restored in subsequent periods. It is a registered ancient monument by the Fine Arts Department and represents the early spread of Buddhism in northeastern Thailand.

The stupa is believed to enshrine Buddha relics and remains an active object of veneration for Buddhists in Phu Khiao and Chaiyaphum. It serves as a center for merit-making and local religious ceremonies, particularly during Buddhist holy days, and is regarded as a sacred symbol of the community's heritage.
