Wat Pho Chai is a historical sanctuary of immense cultural and spiritual significance to the Thai Yo people along the Songkhram River. Established around 1901, the temple’s most prized architectural gem is its "Sim," or ancient ordination hall, constructed in 1944 during the height_ of the Indochinese artistic era. This building is a rare masterpiece resulting from the collaborative efforts of Vietnamese craftsmen and the devout Ban Na Ngiao villagers. Its design features a remarkable fusion of styles: the core structure follows traditional Isan vernacular architecture, while the intricate stucco decorations are heavily influenced by Vietnamese art, complemented by arched doors and windows reflecting French colonial architectural motifs. The hall houses a sacred principal Buddha image in the Maravijaya posture, which has remained an object of veneration since the hall's inauguration and is preserved in its remarkably pristine original condition.

The temple is also profoundly revered as the residence of the late "Luang Pu Saeng Janthawangso" (Phra Thep Mongkhon Watcharodom), a highly distinguished master monk who lived through five Thai reigns until his passing in 2022 at the age of 111 (or 102 according to official civil records). Luang Pu Saeng was widely respected as a "Su-patipanno" (one who practices well), known for his immense compassion, mastery of Vipassana meditation, and extensive knowledge of traditional herbal medicine. Under his guidance, Wat Pho Chai became a focal point for faith and religious education in the region. Today, the temple stands not only as a place for religious ceremonies but also as a vibrant cultural heritage site that embodies the lifestyle, beliefs, and unity of the Sam Phong community spanning over a century. It remains a major destination for visitors and pilgrims seeking to pay their respects and study the invaluable local arts of Nakhon Phanom.
